Thanks! Those are great ideas. I've often thought of putting something behind to block that stuff. Through all the recent battles with algae, I kind of forgot.
The stem plants are rather new. I'm still rather nervous of pruning. How far do you cut back when pruning? Cut back 2/3 or 1/2 of the growth?
I'd like to add some fish, but I've not been so good at chosing. I seem to get fish that have too much of a bio load. Any suggestions? I was considering looking for some dwarf cichlids, or maybe a few schools of tetras. I'm worried about it though. I don't want to have another algae problem on my hands.
