about a month ago one of my oscars was showing a swimming bladder infection im not a vet just a pet owner with google access so any way at 1st he was swimming on the side but by week 2 he just laid flat on gravel i read that aquarium salt may help so i tried it 3 days later he came back to life hes better then ever they both have a much better color now espeacialy when moody they turn super gray and my other fish seem to heal alot faster i just added a red midas who beat the **** out of my gt his scales were gone on one side 2 days later they seem to be healing nicely i think this is one product def worth investing in other then over filtration and a good food source all my fish were raised on hikari gold just introduced a bit of worms feeders and beef heart colors are out of this world
