360_F_366160287_1O7OjMCIjv0XCpVAltN8y35N8w6MVbeN.webpI am happy to post the first Tin Foil Hat (meaning uncommon and unsubstantiated theory) thread.

Dosing a carbon source to an aquarium is a long-standing technique used in the reefing hobby to lower NO3 and PO4 through bacterial means. Vodka is a pure carbon source in addition to being a pretty good drink and is often used. Essentially, the theory is that bacterial populations in our aquariums are limited by the easy availability of organic carbon (not the type you are bubbling into it). By increasing the availability of organic carbon, you increase the bacterial population in your aquarium.

Bacteria are living organisms like our plants (and you and me). They respire and need a food source to grow. When they multiply and grow, they take up O2 by respiring and they take up NO3 (and to a lesser extent, PO4). This essentially competes with our fish and plants. We don't want that. Or, do we???

I did a podcast on this back in 2015 except I talked about dosing vinegar in your aquarium back then. It's the same thing as vodka but cheaper and not as much fun to drink. I'm proud to say our friend @Marcel G referenced my podcast in one of his posts.

What most people don't know (because I haven't told anyone) is that my thinking on this has evolved since 2015. I now follow a very focused method to my tin foil madness but please hear me out. Here's the story.

Ryan over on BRS TV was just starting to explore the hidden benefits of the aquarium microbiome in an effort to understand why new reef aquariums go through an ugly period when started. He was testing a dark start to avoid algae and allow bacteria to grow instead. People thought it was to cycle the tank but that wasn't the only point. The point was to give the microbiome time to grow and take up space. The theory was that if you allow bacterial to colonize the reef tank's rock surface, then it isn't as easy for algae to grow on it.

This got me thinking and so I put it to the test in a planted aquarium.

The theory was: Can I get bacteria to grow quickly in the initial phase of a planted tank so that algae would not be able to capitalize on the initial instability?

I've done three planted tanks since that time and in each one, I've dosed vodka daily for the first two months. I'm actually doing it now with my re-scaped tank.

The outcomes (and by no means scientific evidence): I've avoided the nasty startup algae that many people get. With the current tank, I'm even avoiding the usual fungus you get when you use spider wood in the beginning. Frankly, diatoms and dinos have also not been a problem.

All of this is observational and could be explained to be as a result of other reasons. However, after three times, hmmm... maybe there is something there. I do see my SAE's constantly nibbling on surfaces that I assume are covered with biofilm.

My completely unscientific guess is that the carbon dosing is causing bacteria to grow quicker than algae can. The colonize all available surfaces. By taking this space, algae has a tough time fixing itself to things, including plants. Bacteria can and will colonize the surface of plants and there are studies looking at the interaction of bacteria and leaf surface. I assume that the bacterial has also out-competed (is that a word?) the usual fungus I get on spider wood when submerged for the first time.

Now, some cautionary words:
  • The first time I did this I dosed too much and got a massive cyanobacteria outbreak
  • I have a well oxygenated tank, as bacteria will take oxygen away from the rest of the inhabitants
  • I dose a small amount (.8 ml per day per 25 gallons)
  • I stop dosing as soon as I feel the plants are growing well and can outcompete algae
So, now that you know about this, what do you say? Snake oil? "Art's lose his marbles?"

Following @Dennis Wong advise to hold growth variables as steady as possible to avoid transition stress has been my single greatest tool to aquatic plant success.

I am fortunate to have Tap Water that is consistent all season with 6 ppm Ca, 1 ppm Mg day in day out all year. It is consistent because the water utility adds most of the Calcium and Magnesium in it.. the source water is extremely soft. The head of the water department has told me it never gets close to their target. They continually test and adjust the feed to hit target.

It is simple enough for me to just add gypsum and epsom salt to boost it to what I want.

Helping a fellow member here who is starting a 75 gallon tank in an apartment. Ro unit is simply not an option for him in the apartment for now. schlepping bottles of RO for a 75 gallon would also be a hardship. It is a tank just for family enjoyment and not intended to be a competition tank. He will be dosing diy ferts, high light and co2.

His public water supply has an average DGH of 8 with reasonable calcium magnesium balance. But the Seasonal variation is between 4.5 DGH and 11.2 DGH…

In the situation where RO is not currently an option what would peoples responses be?

At 8 DGH steady throughout the year, I would probably just go with it.

It would be easy enough to test tap water DGH before doing a water change. It would be easy enough to create a table to alter how much to-adjust gypsum and epsom salts as tap water hardness decreases with seasonal shifts down to 4.5. But the question is for the times it hops upwards to high end of range.

One could schlepp bottles for those weeks and hope those weeks are outliers…

Or one could simply target a higher DGH all of the time in the interest of stability..

So I understand the potential issues, but not enough of what numbers matter…

Am I overthinking? I know @Dennis Wong has said the Carbonate hardness has a bigger impact on plant health than General Hardness,

Is ranging General Hardness less of a concern?

Water report indicates 3.5 DKH with no report regarding seasonal variation..

Hello Everyone. After a short 2 month wait, I finally received my 6', 235g Planet Aquariums tank. I've decided to document the build here as a way to document it's growth as well as, and maybe more importantly, seek advice as I've already stumbled onto a few 'problems'. So, without further ado, here is what I have so far:

Tank - 235g Planet Aquariums Mega Matrix (72" x 30" x 25")
Sump - 60g Breeder
Lighting - Skylight Hyperspot M (x2)
Mechanical Filtration - RedSea ReefMat 1200
Additional Filtration - Poret Foam (yet to purchase)
Return Pump(s) - Jebao DCP-10000
CO2 Reactor - Yugang from ARC
Dosing - Chihiros 4-Head with Magnetic Stirrer
Heater - 500W Titanium
Controller - Neptune Apex with pH and temp probes
Auto Feeder - Avast Plank
ATO - XP Aqua Duetto using a 35g Brute container filled with RODI water as source water.
Hardscape: UNS Controlsoil - Brown
Pacific Driftwood
Black Sieryu Stone

As a general thought at this point, the Apex will have some basic functions - control the temperature (77-78F), monitor the solenoid on the CO2 regulator should pH venture outside of acceptable ranges, and control the auto feeder. A 'feed mode' will be activated which will turn off the return pump prior to the auto feeder running so that the food is allowed to be eaten rather than washed into the overflow and into the sump filter. Aside from that, not much more is necessary other than simple on/off control for the return pump as the lights are on their own controller.

Controller and board:

That's about all I've gotten done so far. Still working on fiddling with the hardscape on the right and then start on the left side. I'm open to any suggestions thus far and thanks for following along!

Main idea/inspiration:​

Since my main 150p aquarium is in our front room and is the first thing we and our guests see, I can't afford to experiment much with it. I also spent like $600 on aquasoil to fill it, so I thought I'd like to try something different.

This tank will be 100% BDBS substrate, no fertilized substrate. No root tabs (yet), no aquasoil. Only water column fertilization, to challenge myself to see whether I can grow plants well without aquasoil or not! Inspired by the @Burr740 BDBS journals and many other amazing inert-substrate aquariums out there. This isn't a dutch style, only a general "garden" style tank.

I came into some Hygrophila polysperma "white" by Tropica recently. Grew it out and it seems to be able to be shaped into good midground bushes so I decided to create a layout to showcase it. Contemplated whether to use it as the only white plant in the tank, but decided to use some Anubias white petite as well so that the white polysperma doesn't stand out awkwardly.

This is my first time using a reactor. I have a Landen 100p (40x18x18 inches) and just received my Aqua Rocks Colorado Stainless Yugang Reactor. I had a spare Eheim 4+ 350 so it's now hooked to that with just foam filtration. My other filter is an Oase Biomaster Thermo 600 with an 850 head. I'm a little confused on the initial setup. I have my Co2 turning on at 9:30am, lights on 12-8pm. I have the offsets at 50% of the reactor, and the surface area is 4 inches larger than the calculations said I needed.

I know that contact time is the factor so my Eheim is about 50% flow. Do I initially increase the Co2 rate to purge the air out of the reactor, then dial it back so i'm seeing off-gassing every minute once I'm reaching my ppm? I'm using a Co2 Art Elite Pro regulator. My psi sits between 35-40 on a 20lb tank. Co2 is easy for me to get and cheap so I'm not concerned with excess. There's not a lot of information I can find on these so anything helps. Thanks for reading!

See this post regarding AR Mini trimming/planting, and this post regarding Cyperus helferi trimming and planting!

I have hardly seen this subject talked about enough, but I think that it's one of the biggest reasons contributing to beginner's algae-filled downfalls! If you're buying plants from big stores like Aquarium Plants Factory (really good btw), Buceplant, etc. 90% of the plants you are receiving are terrestrially-grown.

Here's an important fact about terrestrially-grown aquarium plants

100% of all terrestrial leaves, when submerged under water, for any plant, will eventually get algae and die.
Some can take a while (anubias, java fern, cyperus helferi), while others will either melt (Crypts) or quickly get algae (AR Mini, Staurogyne repens, stem plants, etc)

But what about buying submerged-growth plants? From hobbyists, or BurrAqua, for example?

There is still a chance that your tank's conditions are different enough that many, if not most leaves you plant, will melt/die/attract algae.

How do we fix this? By leaving only enough leaves for the plant to continue to absorb light and put out new growth. Usually the top 4-6 leaves for stem plants.

1786937485251.webp

It's a lot of work up front, but you will MAJORLY reduce the amount of waste, DOC 's, and algae-inducing scenarios if you trim your plants before planting.

I've done this in ALL of my tanks in the last 4 years with great success.

The easiest way to do this is with stainless squeeze scissors over your sink:
1786937752576.webp
Here's the ones I recommend.

Yes, it takes a ton of patience. But if it could make a big difference in preventing the 2-3 month algae bloom in your tank, would you do it?


Here are some specific plant examples:​

For most true stem plants, I like to leave 3-4" of stem, trimming roots if necessary, and leaving only 4-6 of the freshest leaves. More than that, they will eventually be algae magnets. Less than that (like 2 leaves only) they might not survive the shock.

1786937664009.webp
Lysimachia nummularia 'Aurea', only a few top leaves left, 3" of stem.

1786937955613.webp
Hygrophila corymbosa. Note how I left the leaf nodes on the stem? That's where roots will grow from. Almost all stem plants need nodes to grow roots, even if you've removed the leaves from them.


1786938009235.webp
Terrestrially-grown AR 'Mini' from APF. See how I did the same in this thread for my previous tanks.


1786938082744.webp
This Anubias barteri var. coffeefolia was grown terrestrially (often called 'emersed' or emergent) in a greenhouse. I removed all but the newest 3 leaves, and trimmed the roots too. Terrestrial roots are quite different from submerged with certain plants.


1786938248454.webp
Almost ALL Cryptocoryne species are grown terrestrially. These plants grow as a Rosette, where the inner-most leaves on the "stem" are the freshest, and the outer-most are the oldest. I removed a TON of old terrestrial leaves, leaving just enough for the plant to be able to grow new submerged leaves in my tank as quickly as possible, while leaving as few algae-attracting terrestrial leaves as possible. I also trimmed the roots, which were 5" long upon receiving the plant.


1786938372325.webp
Lobelia cardinalis 'mini'
1786938398546.webp
Penthorum sedoides
. Would also look very similar for Staurogyne repens, too.


Did you know that Blyxa japonica is actually a stem plant? It looks like a rosette, but it's actually a squat, wide stem plant. The lowest/outermost leaves are the oldest, and even though this is a true aquatic plant with no terrestrial form in nature, I know that it likes to throw a fit and melt a good portion of it's oldest leaves when transitioning to my tank's conditions. Here's what it looked like when I received it from @Burr740:
1786938548455.webp
1786938557694.webp
Nice and trimmed up. Less problematic at the 1-2 month mark in the tank's development, I know it!

What about delicate/feather plants?
They're super annoying to prep. I still only keep the top 3-4" max.

1786938618138.webp
With Myriophyllum mattogrossense 'Golden', I only keep a few inches and still try to remove some of the lower leaves that would otherwise just rot by being buried in my inert sand.


1786938680672.webp
What about Myriophyllum sp. "Roraima"? F*ck that. Nightmare to trim lower leaves, just trim it to 3" (not pictured) and discard the bottom when planting.

Curious what you guys think! I know I could receive plenty of "I've never done this, my tank has been fine" but I'd recommend trying it first before having a strong opinion of it ;)

By the way, all plants pictured were actually used in my upcoming 120cm Showcase tank:

Well I’m done talking about it, it’s time to get this journal started.

I have been really out of it the last year or so in terms of maintaining my own tank, mainly out of frustration with time constraints and inconsistency with dosing etc. However, I have now acquired a dream tank, rimless and with low iron glass like I’ve always wanted. While I loved having a sump and prided myself on putting it together, I’m past that desire. The AIO allows the same benefits with hiding equipment, and overall easier maintenance without climbing in and out of cabinets. Now onto the details of this build.

Tank: Planet Aquariums Tideline 62 Gallon AIO Lagoon

Filtration: (2) 250gph pumps on either side of the tank with center overflow into socks (I’m going to punch holes in the socks for now and stuff with polyfill, reviews state the socks clog way too quickly and there is no replacement sock as the insert is not the common round style). The baffles will be stuffed with the poret foam I have already from my sump for extra mechanical/biological.

Substrate: The bottom layer will comprise of bagged pond soil/peat/earthworm castings/ STS. This will be a thin layer and will mainly act as filler to raise up the cap of APT Feast. This is similar to a substrate setup I did when I first started back up in 2020, And that tank did very well. While capping with sand and relying on the dirt to feed the stems worked well, it did require a little more effort on my end with dosing. I don’t trust myself to be as diligent as some members on here are with their inert subs, so I’m taking the mulligan and using aquasoil as a cap, hence, “dirty soil.” This will be another island style layout, and the surrounding substrate will be comprised of Caribsea Carolina Creek Sand.

Hardscape: River rock (local hardscape center sourced) and malaysian driftwood. I have recently acquired another large piece of wood and I’m sourcing new stone this week, as what I have just isn’t meshing with my current vision for the tank.

Plants: …. I have not solidified my vision of what this scape will look like just yet as I haven’t been able to setup the hardscape to outline the island. The plan is to use a good amount of colorful stems, epiphytes, and potentially moss.

Lighting: I will be ordering the Week Aqua Z400 this week and am excited to test it out.

That’s all for now, more pictures and details to come. I should hopefully have the hardscape setup by the end of this coming week after acquiring more stone and wood.

CO2: Almost forgot, for Co2 injection I have made a DIY Yugang with a locking food storage container. It will be stored in the cabinet and the hook will feed into the return pump chamber on the right. I initially was bummed that I had to sacrifice storage to fit a 5lb CO2 tank under the stand, which also meant getting rid of of the 20lb tank I’ve only been having to fill twice a year. @GreggZ Will appreciate this, my awesome father in law suggested that I hide the co2 tank in the pantry closet which is directly behind that wall and just drill a hole for the co2 line. Since my father in laws word is pure gold in my wife’s eyes, that suggestion was approved! He’s just as much my dad too so I appreciated him supporting the project 👍🏻IMG_3331.webp

Hey all,

I’m a week away from cabinet making, waiting on supplies but managed to find some great driftwood this weekend. This is in my workshop so I’ve just cut a bit of cardboard to start playing with ideas for my new 1200x450x450 rimless tank. You’ll have to look past the background and lighting for now please.

Which design do you think I should progress?
This will be a more nature style scape with limited stem plants and mostly crypts. I’m not keen on trimming all the time and prefer the form of leaves.
I will likely use some aqua soil in mesh bags in the deeper areas which will be capped with an inert blond sand as this is my best available option here.
I will start a journal for my stand build with one of these ideas.

Style 1

Style 2

Style 3

Noting that there will be a little trimming required to sort final placements.

I’m often out and about working in the field and stumble upon breathtaking examples of often overlooked and under appreciated slices of nature that Florida has to offer.

My neck of the woods is filled with marsh/wetlands ripe with both native and invasive wildlife of all flavors; I want to start a thread where I can document and share.

I’ll update this thread whenever I capture something noteworthy. Much of what catches my eye is aquatic flora, but I try and document anything captivating. I hope you find this as beautiful and fascinating as I do.
