I have a SW, 20k gallon, in-ground, gunite pool, built in 11/07.
I have a few questions for a rookie pool owner:
1. We have very soft water. About a month ago, my water tested at 100 ppm. I added 25 lbs of Hardness Up and my level now reads at 230 (which I believe is acceptable). Today, for the first time, I noticed white flakes settled on the bottom of the pool. Are these calcium deposits and are they a "by-product" of the Hardness Up? Is it temporary?
2. My chlorine generator has a very hard time keeping up with chlorine demand. The last few times I've had my water tested, it's shown absolutely 0 FAC and TAC. I shocked it for the 2nd time in about a week today. Is it normal to have to supplement by adding Chlor-Brite or Chlorine tabs in my skimmers to keep up? I thought I was getting away with that with the salt water pool.
3. Am I wasting my money on Pool Perfect with Phos Free. I bought it at the recommendation of my local pool company. My phosphates were at 100ppb. It was suggested I add 2 2/1 capfulls per week to keep the phosphate level down. Big expense.
Here are my other readings if you need them:
CAlcium Hardness 230
Salt 4000 (I know this may be a little high)
Thanks for all your input and expertise! I'm glad I found this site.
