Flow Setup
As plants do not move (unlike animals), they depend on flow to bring air and nutrients to them. Good flow is hugely impactful, yet challengingly 'invisible'.

Filter Intake/outtake placement
I get a lot of air roots on my ludwigia and rotala for the "not dense enough planting" reason mentioned in that article.@Dennis Wong has an article on this

Messy aerial roots?
“Aerial roots” refer to roots that often grow out of the internodes of stem plants midway up the stem, above the substrate. Why do these roots appear? Are they cause for concern? What can we do if we find them unsightly?www.2hraquarist.com
Comment: baby brine shrimp is stupid easy to grow at home. Really.

I looked into this too since my previous PAR meter was way off, and I didn’t want a repeat issue—it’s one of those “set and forget” things. I did some hands-on testing with my iPhone 15 Pro and the official Photone diffuser, using the full LED spectrum setting and an underwater phone case to measure PAR in the water.So here is a detailed explanation of a mathematical formula for a close approximation. He asked me, but then figured it out himself, lol!
Ive used this for a few years. For most part like it. Unfortunately it doesn’t hold up, lid cracked in half. But the duct tape Im using to fix it is!
Good news! Thanks!I looked into this too since my previous PAR meter was way off, and I didn’t want a repeat issue—it’s one of those “set and forget” things. I did some hands-on testing with my iPhone 15 Pro and the official Photone diffuser, using the full LED spectrum setting and an underwater phone case to measure PAR in the water.
Because my lights are suspended from the ceiling, I was able to swing them out of the way and compare readings in air vs. underwater. The two values were essentially the same, both fluctuating in the same range (for example, 60–70 at substrate level). I repeated the test on both tanks and couldn’t see any difference between the air and underwater readings.
So take that for what it’s worth—my water is crystal clear, which might make a difference. Hope that helps!
Yes this is what I think is intuitive. Just strange to see people putting the inflow and.outflow on opposite sides of the tankAnd this!

Thank you, this looks worth a try. The plants I want to move are large leaf anubias and crinum, so they won’t be too hard to visually inspect after the treatment and also maybe to carefully wipe down every individual leaf for stuck on eggs.I was impressed with this experiment, so far I have found this to work beautifully
I know you received some replies, and I haven't read everything yet. Just by chance, I saw this ad on Instagram today. It might help you. I don't know anything about this product. Never tried it. Maybe if you have an empty tank you could pre-treat this way.My question is:
Is there a “guaranteed “ way to clean snails/snail eggs off of plants before they go into your tank?
I found them at Glass Aqua, as well, but not available to me anywhere in Canada. The bottle only lists “Snail paralysis agent” and “Snail stimulate agent”, and I can’t find an msds sheet on the product. It says they are not 100% effective, in any case. Thank you for the suggestion, though. If it were available, it might be worth it in a quarantine tank.I know you received some replies, and I haven't read everything yet.

Has anyone tried it? In my head I wonder if they are just alum tablets

I found them on Amazon here, but yeah, still might not help you. Worth a look though.I found them at Glass Aqua, as well, but not available to me anywhere in Canada.
Well, that’s certainly better than the plastic soda bottles I was using.
I have an Eheim 350 skimmer and use these aftermarket parts on mine. The intake guard keeps tank inhabitants out (except tiny snails) and the outflow really diffuses the strong current to keep plants from bending over.The files are shared online but this seems to be a popular option from an Etsy seller.
Seachem Tidal HOBs have a built in skimmer. Might be worth an upgrade. I used one on my short lived 20G farm tank and it was a good filter, what I would stick with if I didn't prefer canisters.
Been meaning to get something clarified from @techman81 . Do you know where the 3D printers files are for these parts or is my only option to buy these already made?I have an Eheim 350 skimmer and use these aftermarket parts on mine.

I'll add that I cut my own foam filters for dirt cheap.
