I was having a discussion with a former LFS owner and we were discussing tanks stocking and water quality. It got to the topic of aquarium salt and adding it to tanks. He told me that in almost all his tanks he dosed them with aquarium salt. We got into the discussion of some particular fish and he was mentioning that in most cases all the fish in the tanks seemed to color up better and be more active with the addition of the salt. Does anyone here have any more information on this or does anyone do this?
