I've been using the test strips and just recently moved up to the 6 way test kit from walmart. Our AG pool has been open since mid-May. We keep the solar cover on it when not in use.
Chemicals tests are:
On occassion I've been putting a chlorine tab in the skimmer (keep the pump running until it's gone). Nothing seems to move except the FC going to zero and that's when I drop in a tablet. The water has been clear since we opened it up and cleaned up the debris from last fall (took a week for the guy to come out and put the cover on after we filled it last fall ).
I did uncover it tonight just because swimming in 91 degree water is not as refreshing as 88 degrees. I will put the cover back on tomorrow morning.
So should I head to Menards and get the muriatic acid or to the pool store for stabilizer? Or do I dump in some bleach and borax according to the pool calculator?
