Can you please share the plant list, fish list, substrate, filter and your water change frequency?
I've got some American Vals in the back, Some Hygrophila in the back corners, Amazon swords in the middle and right, Wendii in the front right and left and middle, frogbit as a floating plant, and chain swords as cover(still filling in). I don't know the name of the tall plant on the left.
Right now i've only got 2 dwart neon rainbows, 2 rummynose tetras, 9 neon tetras, and 3 rasboras.
I use a Fluval FX5 filter. I have 260w of Compact Florescent with and extra 50w of grow lights that i never use...but could if i needed. I use Seachem flourish black gravel substrate.
I was doing 50% water changes each week but had a horrible time with algae and brown diatoms. Stopped doing that and now it's probably 50% every 2-3weeks and things seem better that way. My city was has a pH of almost 8.3 and is hard so changing it is hard. They are also messing with the chlorine a lot that has killed fish when i didn't double or triple the dose of dechlorinators.
I used to use dry fertilizers and had a CO2 system running but gave all that up when i couldn't find a good balance. The plants ended up doing much better when i didn't try as hard. I sometimes add a fert tab or some flurish and iron for the swords but not often.
