Hello. Long story short I've decided that my pool "professional" didn't do as much as he should after creeping around on this website and realizing that 10-20 minutes a week probably wasn't enough time to keep the pool in tiptop shape. I purchased the tf-100 test kit and the numbers are as follows.
So the pool is almost exactly 1 year old and the only problems I've been having are scaling problems. It's known that we have really hard water out here so I just kind of accepted it as something I would have to deal with. However, I decided to test the CH of the fill source (city water) and was surprised to find that it tested at 200. So surprised that I repeated the test 2 more times and got 200 each time. I consulted pool math and understand what I need to do to adjust the rest of the other results to optimal. My question is 2 fold.
1) Is there a way to lower my CH without replacing 80% (according to poolmath) of my pool water?
2) If not, should I wait until it is done refilling and then test again to determine proper course of action?
Thanks in advance.
