I'm new to the forum, and new to test kits.
I've been using trichlor tablets because... well that's what the store was selling me, and they seemed to fit nicely in my chlorinator. But i couldn't ever get my chlorine levels to settle down, so i came here and bought a test kit.
Lo and behold, i find my CYA to be crazy high.
FC = 5.5
CC = 0.5
TA = 100
CH = 390
CYA = 120
(fyi, i got a CYA value over 100 by using jblizzle's suggested method of testing 50/50 pool/tap water and doubling the result.)
Here's my question:
Pool calculator says to bring down CYA i need to replace 67% of my water.
That's an awful lot!
We don't even empty the pool that much when we close it for the season.
(The contractor said something about how the concrete structure will "float" out of the ground without the weight of that water)
So provided i'm an a-hole who is [s:2xjivxte]unwilling[/s:2xjivxte] reluctant to empty the pool in the middle of the swim season, what do these high CYA levels mean for me?
Any tips or advice for dealing with high CYA?
Or, would you rather berate me for running this high CYA? i guess i'll take that too. Maybe you'll shame me into emptying my pool.
If i keep using the trichlor i'm assuming the CYA will continue to rise. Does that even matter at this point?
That's actually a serious question. Any reason not to keep dumping CYA into the pool via trichlor pucks now that i'm already at such a high level?
Any help or advice is appreciated.
This stuff is all totally foreign to me.
