Hi, I use a Penn-Plax Cascade 1000 on a 285litre(75USgal) freshwater planted tank, containing mainly small community fish.
The filtration works from the bottom-up on this filter. In the first tray I have a coarse filter sponge, in the second tray I have a thin fine sponge followed by carbon. The third tray has a thin fine sponge but that is it, I assume it is left empty for whatever I want to put in there.
Any recommendations?
