First thank God for this resource...
Been ready for the better part of an hour...
I am amazed at some of the misconceptions I have had and that I have been told by commercial pool companies.

We (my wife, 2 little girls and I) just moved down from Ohio to Louisiana "HOT"
We inherited a small pool 15x48 (vinyl liner obviously)
1/2horse pump (1500gph) and sand filter.

Pool was fine crystal clear for weeks..
We had a set of severe storm here for almost a week.
90+ degree weather, pump off (no power) = ALGAE

I shocked it with super shock - no good.
I bought (Wal-marts "Green to blue shock")
Followed directions, all green stuff coagulated and fell to floor....
Problem ANY water disturbance unsettles sentiment and I am back to green cloudy water...

I have read a few threads here so I will say it now;
2morrow I will get a cheap tester (walmart) until the I can get a better one from the Amazon link.

Thank u in advance
