I have a fiberglass pool.
I just put in another 4 pounds, mixed with water before I threw it in the pool.

So hopefully in the morning it will read something.
Or should I add more tonight?

My chlorie is nill also, just put pucks in the chlorinator and one package of shock...again I have stuff left over....but I think I might go get some bleach now for a quick fix?

thanks for the quick help!
