3. Muriatic Acid
Read the warning label. Acid is very harmful & dangerous. It is also an important chemical in water chemistry. It lowers pH & helps chlorine sanitize the water. Don’t add more than 1/4 gallon, apply to the deep end, don’t pour over objects in the pool such as lights, keep the pump circulating for a minimum of an hour before swimming.
