I plunged into the hobby last year with my ages-old 20L, and eventually moved up to a high tech 40b seeded with plant packs from Burr and Herns. The 40b never quite got the fertilizers and attention it needed, so after moving houses, I decided to start fresh with a 20x20x16, 28 gallon rimless cube tank.
I built the stand with 3/4" pre-finished maple plywood, and trimmed it with more maple for a nice clean look. Door has yet to be mounted.

Plants came in a big package from Rare (5-09-18). There were a couple species that didn't survive the journey, but for the most part everything came healthy and ready to re-establish in my extra hard 7.8PH water.
AR Mini (From Burr)
Erio sp. Vietnam
Erio sp. Malayatoor
Ludwigia sp. Red
Ludwigia sp. White
Poaceae sp. Purple Bamboo
Rotala Mini types 1, 2, and 4
Rotala Mini Butterfly
And the main course: Thread Algae! I pick off a toothbrush or two full every other day, and I'm currently trying to figure out how to get rid of it.
A couple generations of Dalmatian Mollies. Great for picking off dead plants, but seemingly ignore the hair algae. Shucks.
Aquaclear 50 with CO2 chopstick diffuser and 100ml Purigen
CO2 at 3-4bps getting a 1.0 Ph drop from 7.8 to 6.8
Fluval 100W heater set to 76F
2" BDBS Substrate
Koralia Nano 240gph
DIY Light fixture tuned to a pink-purple hue
(2) Cree 1304 5000k led (50%)
(2) Cree 1304 2700k led (20%)
(8) Semileds Deep Red (20%)
(4) Semileds Royal Blue (20%)
Set to a 7 hour photoperiod at ~60PAR. Full brightness is 220PAR, which I hope to ramp up to once everything gets established.
My old bottle of Thrive just about ran out, so I decided to start DIY EI ferts. Since Burr's tank is so successful, I wanted to emulate his fertilizer regime with a 3x Macro dose after water changes, and 2 doses during the week. Each dose gives 6 ppm KNO3, 0.5 ppm KH2SO4, and 2 ppm K2SO4. Micros are basic EI-dosed CSM+B for 0.15 ppm Fe daily.
Here's a comparison shot right after the last water change. The water gets cloudy the day after 50% water changes, and hasn't cleared up in the past 3 water changes. When I started the tank I kept the bio-media from my prior tank, and testing shows zero nitrites and ammonia. I got a bag of purigen thinking that it would clear up the water, but no dice on that front. Could it already need re-charging after only a few weeks?
Current plans are to wait it out while pulling algae out every few days, keeping with the 50% weekly water change schedule. Plants are almost ready to trim and re-plant! All plant locations are tentative right now, since it took roughly 5 hours of trimming and planting to fill the tank originally. I think I'll move the central rotalas further back, and the bushier green plants can be more centralized. The main goal is to grow these enough to transplant into my work-in-progress 75g, where they'll all have much more room to grow out.
Edit: Here's a bird's eye view of the layout. Should I uproot and spread out the erios?
