I read that you can use a Hydrometer or a Refractometer to test salinity levels. I have been treating my 210 freshwater tank with API Aquarium Salt as my smallmouth bass has a little fin rot. I have been doing the one tablespoon per 5 gallons and when I do water changes I figure on about how much water I take out to replace the salt. However, I want to make sure that it isn't too salty or not salty enough to treat my fish.
How do I test this?
My ph dropped from 6.6 to 6, so I think that I may have too much salt in there and it brought it down.
