I'm a new pool owner/maintainer. My pool was plastered/filled last winter, but they closed it without adding the salt, so I just opened it a couple of weeks ago. They had originally just cleaned it, shocked it, and balanced it, and threw in some chlorine tabs to make it swimmable for the Memorial Day weekend, and then came back a couple of days ago to add the salt and set up the SWG. I had been watching the levels and adjusting them prior to the pool guy coming back, but the one standout was that they never added any CYA (my initial readings were 0). After two weeks on trichlor tabs, the level was somewhere between 20 and 30 (I'm not that practiced at that test yet), but definitely nowhere close to the TFP suggested 60-80.
When they finally came to set up the SWG, I asked about the CYA level, and he said given that I have a pool cover and will be keeping it covered whenever I am not using it (little kids == scared wife == pool definitely closed all the time), I shouldn't need to worry about the CYA level or the sun burning off the FC.
Any thoughts on this? I don't really have a sense of just how fast sunlight will reduce the FC -- when I test in the morning, the FC is in the 3-5 range from the SWG. I just want to make sure if we have a long day of the kids playing in the pool my levels aren't going to drop too low.
Since I know you'll ask
FC 5
CC 0
PH 7.8 *** I added 2 quarts of MA
TA ~100-110 ** This has remained stubbornly high since they filled the pool
CH 275 ** planning to add some more to get up to the TFP recommended 350-450 for SW pools
CYA 30
Salt 3300
Temp 88 degrees!
