On Friday I got the pool water up to a nice temperature for the first time but the water started to go cloudy. I could still see the deep end, but the water became dull and whitish looking.
If I plug my numbers into pool calculator, it says that the water is hugely out of balance. I've been fighting a high pH ever since I got water in the pool two weeks ago, and this along with temperature seem to have a huge effect on the CSI.
I've let the pool cool down a little and have been continuing to add acid. When I pour the acid in, I can literally see the water sparkle where the acid is added. But after a short while the water starts to go dull again, not as bad as before, but certainly not sparkley.
I've been using dry acid, since it's easy to get hold of in the UK, unlike hydrochloric acid. The only places I know I could get hydrochloric acid from charge a huge delivery fee that is probably twice the cost of the product, which makes dry acid far, far cheaper.
How much dry acid is too much? I've probably got through 10kg so far. And can the sulphates in the product have an effect on calcium scaling? The water didn't start off cloudy even though the pH of the pool was much higher originally - it's now about 7.7 compared to around 8.2+ 10 days ago - although the water was colder.
In other words, should I really be spending the extra money on hydrochloric acid?
