First of all, AWESOME site. Excellent advice/discussions, and I'm very glad to be a member.
Brand new pool just finished construction with RiverRok plaster about 5 weeks ago. I allowed the builder to use trichlor pucks in the auto-dispenser for a short time until I measured CYA to about 50-60 ppm. Then I shut down the dispenser and am no longer using pucks, only bleach. I'm measureing pH and FC daily while monitoring everything else a couple times per week. As expected, I've been adding acid every day as the plaster cures, but noticing a little less demand. I recently added borax (acid first) to get to a calculated level of 30 ppm (about the only main thing my test wont test for). Note that I am in Texas with 100+ temps. Here are my most recent numbers:
FC - 3.0
TC - 3.0
pH - 7.8 (added some acid after test)
TA - 110
CH - 140
CYA - 55
So far, using the levels and advice from this forum, my water is gorgeous clear sparkling blue, and I really want to keep it that way!
Questions:
I have pucks to use when I go out of town. I assume this will result in CYA levels getting too high, so I suppose I'll have to drain and refill some water if/when this happens (week long trip coming up in a few weeks)?
Since this is a new pool/plaster job, should I wait longer before trying to adjust anything else (e.g. CH)?
Thanks again for a great site!
