I would have also liked to see you add a salt regime when you started your bio-filter. I would ask Jim Held or Bill Cody and get their opinion, being that I am not an expert, but I have killed many fish
Me too but all the literature I have found says adding the salt should not be a problem if added slowly which I did. According to one piece, even if the added salt stresses the bacteria they should adapt fairly quickly.
If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
