No maintenance low tech tank. Nitrates stay around under 5ppm, which requires very little water change. Stocking includes one giant betta and many many neocaridina cherries and pond snails. No worries though, they are the main reason this tank stays algae free without any help from me at all. Only requires top-offs and water changes every month or two. Does require optional trimming though.. This tank has reached its peak natural balance, hoping it stays that way. 2x 6500k 23w CFL, random filter and 100w-ish heater, lights on auto timer. I dose micros every once in a while
