Can you tell us again exactly what is in it? The list is confusing. Well I have learned that Plecos are really dirty fish, I always thought they were a cleaning fish but if he has 3 that are 8 inches that's a pretty heavy load with nothing to clean up after it, except his filters. And he has 3 more of something else 5 inches?
Does he test regularly? can you give us some readings, how long has it been set up?, My canister filter has 4 layers in it and none of them is carbon. Large sponge disks, gravel like substrate, tube like substrate, fine poly fibre. Sounds like he has some of these between two filters? They way you have described the filter mediums it sounds like he has some in one and some in the other.
ok I need others to chime in here, these mediums work together and my thought is he should have all 3 or both in both filters, that way he could alternate cleaning of the poly fiber and sponges and not disturb the substrate..... help all you experts out there!!
