I just picked up a Fluval Edge the other day. I already had the Chi and my only complaint with it was the evaporation, I had to add water every couple of days. Really like the Edge though...put filter media from a cycled tank in it and added two keyhole cichlids.
they just layed the eggs . first batch of german ram cichlid eggs. Hopefully the tiny catfish in the tank dont get them. if it does i will have to move him to another tank. but they were picking on the blekeri when he was in there for a day or two
