Well, we did Picasso's second water change tonight. The water is still hard and very alkaline, but the ph is coming down slowly. His fins still are not doing well. It has not gotten much worse, but I also don't see any improvement. We put a bit more aquarium salt in and am adding beneficial bacteria. The guy at the fish store talked us into getting some Betafix, but when I read the directions it said not to do a water change until you've used the product for 7 days straight and I wasn't sure if that would be good for Picasso or not, so we have not used the Betafix yet. Should I go to that or just keep with the water changes?
