So I'm currently pretty happy with my JBL 901e that i have installed on my 60p. The very low amount of noise, and decent flow seems to fit the tank quite well. However 10+ weeks into the filters life I'm still seeing some pretty high spikes in NO2, despite low feeding and 2x WC weekly with about 50% - and I'm thinking of replacing some of the stock media the filter came with, without having to sacrifice to much flow performance?.
Does anyone have any suggestions to what media/combination I should be using, preferably based on personal experience.
Best regards.
