Hi, my neighbor gave up and filled in his pool recently. He brought me a box of pool supplies he had bought and have them to me for free. I went thru the box and was able to identify them and determine if they were safe except for one item. It is called Pool First Aid and manufactured by a company call Natural Chemistry. The bottle says it is a natural enzyme formula wife organic clarifier to fix pool problems fast like dead algae and pollen but does not list it ingredients. Does anyone know what's in it? and is it safe to use in an on ground pool?
