I am testing it after adding the flakes - about 2 hours or so after I add.
Now I am adding acid to lower the PH - so far 2 times per day as it keeps popping up because of the new plaster.. So I figure at this point I am going to hold off.
I added some more about 20 minutes ago - I'll test it later and if it's close - I am gonna wait for a week and let the water "settle in"
I did give the right gallons at pool calc. Although I must say the pool builder guessed 15K gallons. I went right off my water meter before and after and got 11948.. So thats what I entered at pool calc.
