first pool, first test with the ps234
I have an AG 30' X 52" pool w/vinyl liner that was filled for the first time two weeks ago. I think my volume is around 17000 gal. Please correct me if that sounds way off. My first results are as follows:
FC 5.5
CC 0
TC 5.5
PH 7.6
ALK 240
CAL 130
CYA <20
There was some cloudiness in the cya test but not enough to make the dot go away at 20ppm. I added 2 lbs of cya at open and just added another 1 lb today after the test. Is there anything else I should be concerned about? Water looks nice and clear.
Thanks for your help,
Dave
Re: first pool, first test with the ps234
For the moment, I think you are OK. Your Tot Alk is high--We generally like to see it at 80-120, but in a vinyl pool anything up to 180 is FINE, and up to 200 is tolerable.
But get your CYA straight first. Since your water is clear, and your FC is fine, just get CYA to 30-50 and see how you are. If you get milky cloudiness, you'll have to lower Tot Alk, but if the water is clear, it shouldn't hurt.
You can read up on how to lower Tot Alk in the Alkalinity and calcium forum. Do NOT add more calcium NO MATTER WHAT THE POOL STORE SAYS! If your calcium goes high, with a high Tot Alk, you'll get milky water. Don't use Cal-Hypo to chlorinate either.
