I go out and skim and take a look at the pool every morning and test the water roughly 3-4 times a week. About every other day or two.
Yesterday the water chemistry was perfect.
Son didn't know I tested it yesterday and tested it this morning. It is very high PH. I retested and sure enough it went from 7.6 to darker than the highest color code.
That's the second time the Ph spiked suddenly and dramatically.
Can anyone tell me why that is? The water looks crystal clear. I just used the broom on it the other day. The swg is going 8 hours per day. The free chlorine and combined chlorine are spot on.
I can't think of anything we've done that could cause it. The man looked up stuff with google and said he thinks the kids making whirlpools aerated the pool too much and caused it. Seriously? I don't think so and even if it is, I'm not going to yell and the kids to quite swimming in circles. It's some kind of child requirement in a pool, to make the biggest whirlpool they can, right? ;p
