Review on 🐠 KORDON #31456 Fish Protector – 16-Ounce Aquarium Solution by Alexandria Richmond

Excellent for strengthening the immune system. Use it for water changes or transport so they don't get stressed. Treating them for anything helps them work better and adds extra slime. Anyone who has fish should have it. Your fish will thank you. A good size bottle that will last a long time. The only time you shouldn't use it is when your gills are swollen and full of mucus and you're having trouble breathing.
