After 6 months of battling the problem of high calcium & CYA levels resulting in difficulty keeping FC, TA & PH in balance, I am planning to drain & refill.
Everyone I have talked to, who has looked at the pool, says it appears that the high calcium levels originated due to improper PH monitoring during the start-up of my StoneScapes finish & too much conditioner being added, although my PB will not admit to this, nor will he fix the problem.
Additionally, much of the mini-pebble surface remains unexposed. I have also asked whether I should do a non-drain acid wash to expose more pebble, but nobody will give me a straight answer, not knowing how the pebble was applied. It turns out that my PB used a non-certified applicator for the StoneScapes finish & put the name of a certified applicator on my "Lifetime Warranty". I even had the "certified applicator" whose name is on my warranty, take a look and he was very non-committal, and taken aback by the fact that my PB put his name on my warranty.
After initial fill (remodel) in late March 2014, Calcium was 950. Current readings per the TF-100 kit are:
FC = 5
PH = 7.5
TA = 50
I am planning on draining a little more than half from my 10,000+ gallon pool & refilling; "Pool Math" says 60%.
I have some questions.
1. What is the best way to drain my pool? This is my equipment
2. After the pool is drained, should I re-fill it with my water softener on or off? (It was off when the initial fill was done) Calcium readings when off is 400 and when on is <50. I tested these levels when I found out there was a problem, thinking that my unsoftened water may have been extremely high in calcium.
3. To add chemicals after the re-fill, should I just test the water and go by the recommendations of the TFP Calculator?
4. I try to always use the "Yellow Jug" liquid chlorine. In the event I plan on being away, I will float a couple pucks which I cannot imagine creating a problem; will it?
Any guidance you can provide would be most helpful. I have lost so much sleep over this issue and want to fix it once and for all.
