Going dutchy-er
I decided to do a pretty large rescape to practice a slightly more dutch-inspired layout. Still not a true dutch really, but pretty close!

The bubbles are from plants pearling. Upside down rain!
I'm just amazed at how the Red Tiger Lotus (
Nymphaea zenkeri) grows. I've never tried a nyphaea before, and it's insane. Grows SUPER fast, and pearls more than any plant I've ever seen in my entire life. The leaves literally become buoyant by 1pm, pulling up towards the surface, because of the oxygen they're producing:

Insane.
Myriophyllum sp. 'Roraima' grows insanely fast like Kwyet said, but I love it. Beautiful plant, beautiful contrast.

Blyxa octandra had some older leaves melt and die from the replant, but the new stuff is coming in rapid and green. It's constantly flowering, too. Just a killer plant, maintenance-free green olive colored bush. Love it so much.
Bacopa 'colorata' finally getting some decent color. Not sure why it's so green in this setup, lighting is pretty high. But so are nitrates I guess...

I received the absolute TINIEST
Erio ratnagiricum, here's hoping it will survive!

Thanks for reading!
Water Change: 67% weekly WC (2/3rds removed, replaced with fresh RO water). I used to do 73%, trying 67% to save water and keep things a bit more stable over time.
Lighting+CO2: ~110 PAR at the substrate level for ~8 hours a day. CO2 on at 5am, lights reach full 9am. CO2 sits about 40ppm for entire photoperiod.
Temp: 75F via Chihiros Inline Heater Pro (a few degrees warmer to stimulate plant growth)
GH: I reduced the
GH, and now I remineralize the
GH of the incoming RO water to 27ppm Ca, 9ppm Mg via CaSO4*2H2O (Gypsum) and MgSO4*7H2O. Previously I was using MgCl2, but I like working with this Mg source better. MgCl2 is 'sticky'!
KH: I currently raise the
dKH of the incoming water to ~0.8dKH via KHCO3 (also adds
K for Macros). Less than I was previously, so
KH is still <1.
Macros: After the 67% WC, I dose the incoming fresh RO water to 24-7.2-30 as
NO3-
PO4-
K via a Macros solution of KNO3 and KH2PO4. I also include the
K added from KHCO3 (
KH riser). This is basically a single weekly front load. I then dose 1-0.3-0.75
ppm every morning via GHL Doser 3. Think of it as a single weekly macro front load, and a small dribble of macros every morning to help keep levels fairly stable.
Micros: Running a solution of modified Burr V63 micros (no Fe gluconate). After the 67% WC, I dose 0.07ppm Fe-worth Micros. I then dose 0.07ppm Fe every morning via GHL Doser 3. Total weekly Micros are 0.56ppm Fe, with 67% WC.
