We have a new pool(6 weeks old) and my calcium reads 270. We have a problem with Calcium build-up in the pool. My ph is right at 7.2 but last week it was 7.8. My alkalinity was at 180 when I took over maintenance from my PB. It is now at 110.
I now have calcium spots on some my tile and pebble fina and I have a shoeprint coming through due to the calcium depositing on it(Plasterers came out right after pool build to sand the calcium off of the shoe prints. I had a lot more of them). I was told then that they would come back if we didn't watch our chemicals to keep Calcium from depositing.
We can just sand the shoe print, but how do I keep the calcium from depositing on my surfaces?
Could it just be that my numbers were off when my PB was maintaining the pool?
