I just bought a new house with a pool, first pool I've ever owned. The previous owner used a chemical service, and apparently they came once a week. From what I can tell, they basically add CYA twice per year, and liquid chlorine every week. All that for $50 per month - what a deal, wink wink.
Some things I've noticed about the pool, the water looks pretty clear to me. No obvious signs of algae or anything. Around the waterline tile, there is some white scaling.
I've been reading a lot here for the past week or so, read through Pool School, and just got a Taylor K-2006 test kit today. Here's what I tested:
25k gal, In ground, plaster, North Texas
Water Temp: 76
I was surprised at the FC so I retested it and got the same thing.
My first thought is that the CH is too high and is the cause of the scaling. From what I've learned, I should lower the pH by adding muriatic acid and I think this would then bring the CH down?
I plan to take a sample to Leslies in the morning to see if they get the same readings I got above.
Thanks in advance,
