As I mentioned previously, pool was plastered over weekend and filled Sunday, so now on day four of start up. Plasterers added sequestrant first day (Monday) and one gallon MA and three trichlor pucks in both skimmer baskets Tuesday. Haven't added anything since then.
Tested yesterday evening and got the following:
FC - 7
CC - .5
pH - > 8.2
TA - 100
CH - 750
CYA - 0
This morning it was:
FC - 9
CC - < .5
pH - > 8.2
TA - 100
CH - 650
CYA - 0
So various questions -
FC - is it possible that it rose two ppm overnight, even without any additional chlorine being added? I checked the pucks and they are mostly dissolved, so I'm thinking that number will come down on its own, and I just won't add any for the time being?
pH - has been high since filled. Should I add another gallon MA today?
CH - had risen every time I'd tested it until this morning. Couldn't believe it was at 750 last night. We don't really have particularly hard water here. Then this morning it seemed to come down. But I'm wondering if I'm doing the test exactly correct - instructions just say to add drops until it turns blue, not to swirl while adding, so I've been waiting 'til it really goes blue to record the reading, but it mostly turns blue several drops before it goes all the way, and I think if you swirled it, it would be all blue, so am I doing that correctly, or when it turns blue enough to make it all blue if swirled, that's the reading?
CYA - appears we have none. As I'd mentioned, plasterer said we did not need to add any as we have the trichlor. Wondering if I need to worry about that right now, or let it adjust itself over time?
OK, I think that's all for now. Thanks for all the help so far!
