I've spent the last week or so, reading up on Pool School. My test kit arrived and I've done as many of the tests that I can.
Background - our pump was out of action for about 5 days due to when our fence was replaced, the contractor took the electrics box off the fence and some how shorted the electrics. Took a few days to get an electrician out and by the time the pump was operational, the pool was a swamp. Followed the local pool supply shop directions to kill off the algae (added Green Clean and chlorabrite) but just can't seem to get it under control. We've had a lot of rain here lately as well (Dallas, TX). Wish I had found and red this site before spending the $$ at the pool shop.
Went out of town on Friday evening, pool was in pretty good shape visibly. Got back Sunday morning - algae all over again. Husband swept sides and bottom and added 3lb clorabrite and backwashed. I had just received my kit yesterday and tested the FC - it was 5. This morning, pool looks ok visibly, a couple of bits of green marks on steps and I have just got through running all the tests I can. Here are the results:
PH - 7.4
FC - 0
CYA - >100 (redid the test using the add tap water and it came out at 140)
Alk - 90
CH - 350
One other thing. It appears our SWG is hosed. New one is arriving tomorrow and I hope to be able to fit it. I have been and bought bleach at Walmart in anticipation of further slamming required. At this point, from what I've read, I think I need to get the CYA down and I assume that draining and re-filling is the best option at this point. Am I moving in the right direction ?
