I've read through a few posts here with similar issues, but I think the difference I'm having is the pool is keeping chorine.
Numbers Monday according to pool store, over 24 hours after adding chemicals, compared to my numbers with the Taylor K-2006 if different:
CH 310 I was showing closer to 550, but this is the first year I've used the kit
CYA 45, I was showing closer to 30 with cloudy water (I could still very faintly see the dot when water was up to the top) . I've put a few pucks in a floater to bring up a little bit.
pH 7.6, I showed 7.4
When I got back I proceeded to shock the pool up to 15 with 8.33% bleach and have been keeping it there since, with the lowest I've measured being 12. It's now almost 2 days later and I still can't see the bottom except in the shallow end, and that's not clear. The pool is a good color - just not clear. My pump doesn't show pressure but I've backwashed about every day and a half when the Polaris stops moving and the jets slow down. I've noticed a small difference since starting the shock on Monday, but not much.
Pool was dark green when opened 8 days ago. I had added clarifier late last week but not since since I may have overdone it, adding about 32 oz. over 3 days.
Is this most likely:
- a problem with the filter
- possibility of too much Calcium despite pool store measure
- just bleached dead algae still hanging around and I just need patience
- something else
Last year and this year the Polaris is picking up small amounts of sand.
We've lived here 2 years and haven't changed out the sand in the filter, the previous owners lived here 2 years and didn't leave any records. Before that previous owners were good about keeping up maintenance but Leslie's doesn't have their records.
Thanks for your help!
