Moves are the worst! I thought I had it down too, but my system was too clean and starved itself out. You should hop back into the space with a little nano! This tank is soooo simple, i have done 2 water changes in like 9+ months and it’s so clean because of the low bioload from shrimp that i have to dose nitrates for the plants. No co2, just the light, nitrates occasionally, and liquid fertilizer here and there. With how far the technology has come, a simple nano can be had for well under the price of a keeb! Thanks boss, hopefully I see you on one of my aquarium posts when i finally get around to it
