Hello all! Just curious to find out how often folks clean their canister filters?I have a cascade 1000 and a penguin 330 biowheel filter on my 55.Is this too much filtration?I have heard the biowheel "Could" remove to many nutrients from the water?Any thoughts?This is my first planted tank.My previous tanks have all been semi aggressive so i made sure to get plants that were easy.crypt,vals,java fern,moss,and a couple that i have forgotten the names of.Any comments or suggestions would be much appreciated.
