I've been trying to keep the water as clean as possible after watching lots of discus care videos and my nitrates never go far above 10ppm. My only concern is that the plants need that nitrogen. I know discus really appreciate frequent water changes but what level of nitrate would you all recommend is best for plants and discus together? I am also using a regimen of seachem ferts that I will soon hook up to a doser. My next move is buying a second Fluval 3.0 because I feel like the one isn't enough for this large of a tank as well as getting a timer for the co2 regulator.
