Do I need calcium in a fiberglass pool? I've been studying water chemistry to be prepared for my upcoming new IG fiberglass and can't really answer this question.

Re: Fiberglass Pool
You need to keep a CH level to prevent calcium from leeching out of the plaster. Based on that assumption, a fiberglass pool should not need to calcium. I may be wrong but that is my feeling. Now if you have a heater I think that you do need to maintain your CH level.

Re: Fiberglass Pool
The only other good reason to keep calcium in a F/G pool is if the manufacturer requires it for the warranty--you don't want to give them ANY excuse to back out of honoring it if you need it.

Ahhhh I didn't even think of something like that. Good point Carl.

Re: Fiberglass Pool
I just checked with the heater mfg and it says to keep TA @ 120-150 which is a little higher than recommended on this site and to adjust calcium to 200 300. Thanks for the tip. I never considered the heater requiring calcium. Just trying to sort all of this stuff out before hand. Any thoughts on the higher TA?

Re: Fiberglass Pool
TA of 120-150 should be fine.
