I just have started up a new tank, I'm almost 3 weeks up and running now. these are the specs. Nano Cube 30L Dennerle CO2 (now around 40mg/l) 2 x Dennerle nano light 11w (4 hours on 2 hour break and another 4 hours) ADA Amazonia subtrate ADA Powersand Nano Filter Ferts: ADA Brighty K and ADA Step1 Water changes: 50% after 3,6 and 7 days. after that twice a week 50% I think I have upcomming Rhizoclonium on my moss, so its hard to clean of from there. Should I do daily water changes of 50% and a black out of 3 days? Or anything else I should change or do?
