Gary, all of that is there. You can't really avoid it all. I suck up visible mulm, and do top offs directly over the plants to shake any detritus off that may have settled onto the leaves. There are spots of BBA....I just trim off old leaves on occasion to keep them looking nice is all.
Thanks Kwheeler! At the moment, a lot of bronze corys are in there. You just don't see many of them. I had a CO2 dump a while back that killed most of my fish, and I just haven't replaced them yet. I'll need to soon.
