My pool was completed last month, and we started filling on December 6th. For several weeks, my PB was maintaining the chemistry and has since transitioned maintenance over to me. Since the plaster is still new, the water is cold, and nobody is swimming, I have been taking my time getting the chemistry lined out. Alkalinity is coming down, calcium is now good, and pH is starting to stabilize. I'm waiting for the trichlor pucks to get consumed from the feeder before converting my pool over to salt water.
Meanwhile, I'm taking advantage of the CYA content in the trichlor so I don't have to go purchase any for awhile. But, holy cow, my CYA is up to 40 already and I've only been using pucks for 5 weeks!! If I continue to use trichlor, I'll reach my target CYA before the vernal equinox. I know this site likes to rail against trichlor (and I understand why), but I really had no concept on how quickly CYA can build up. Any non-believers out there....consider yourself warned!
Thanks, everyone, for the great information on this forum! I'm a TFP believer for sure.
