Hi all,
I have a little pool app on my phone that I also use in addition to PoolMath called Pool Pal. It spits out LSI numbers in addition to CSI numbers and I have a real hard time keeping my pool in the non-scale regime for LSI. Here are my numbers:
Temp: 84
FC: 2.8
CC: 0
pH: 7.6-7.8
TA: 80
CH: 390
CYA: 25-35, depends on which day I test, I may need a new sight glass, there's a way to clean these right?
CSI spits out 0.38 and LSI spits out 0.51. CSI says balanced but LSI says scale. I have a hard time keeping the pH down, I use a lot of HCl, I feel.
Currently Home Depot is selling the 10% bleach so I'm using that, but normally I use the 8.25%. Water is crystal clear, never had any algae problems. The plaster is pretty beat up and will need to be redone soon I think. I've owned this pool for two years and the plaster is reasonably rough and there is one spot about a quarter in diameter where the last re-plaster has chipped off. The plaster on the stairs is worn away a little on the edges. I feel like the auto pool cleaner, which is running for four hours each Saturday may be damaging the surface of the plaster as well.
Any guidance on if I should worry about the LSI numbers or just focus on the CSI?
Thanks,
Tony
