Betta Lump

Question
How. much salt do I need in 10 gallon aquarium

Answer
Dianna,
If the tank is for a Betta, no salt should be used. He is a fresh water fish. If you are using salt to help an injury or illness then the ratio is 1 teaspoon per gallon of water or 1 tablespoon for every 5 gallons of water. Remember that the salt is only added to the clean fresh water being put in the tank during a water change. Also, it is very easy to add too much salt so be very careful. Salt also does not evaporate so once the fish has been healed, start removing the salt by doing partial water changes.
