i have a new tank setup running with 4 damsels. the hydrometer i am using is reading 1.032 how do i lower this to the desired level of 1.022? thanks in advance
Holy cow! You shouldn't have put fish in there until the salinity was stable.
To lower the salinity, you need to remove water from the tank and replace it with fresh water. Go slowly, as sudden changes won't be good for the fish.
