Our pool has gotten progressively cloudier over the last few days. My daily tests have been fine. The FC gets down to 2 by the time I test it 1st thing in the AM, so I add LC to get it to 5 according to PoolMath. My pH is a touch high, looks like probably 8.0, but would that really be high enough to make the water cloudy?
I tested for CC and there are none (shocking since we had a pool full of 1-4 yr olds all weekend), but the cloudiness has a slight yellow/green tint to it. Should I do another ONCL test? I passed the one I did a few weeks back when we 1st opened. We haven't backwashed in a little over 2 wks, but we're only up 4 psi from our "clean" reading. Should I just go ahead and backwash anyway? It HAS been pretty rainy over the last week, but the water looks its worst today (Friday), and it hasn't rained since Wednesday night.
It's a black bottom pool, so I feel like it never looks crystal clear the way a brilliant turquoise pool does, but the deep end is usually when I can tell that there's a problem. I'm having trouble making out the dark main drain cover and can only make out the 2 small white things on the bottom there (not sure what they are)
FC: 4 (weekly test result whcih I did today to be sure I was reading my daily correctly)
CYA: 30 (I have another post regarding my skepticism of this number, and since I'm not sure the accuracy I've been hesitant to raise it further)
Hubby really wants to add a clarifier and run the filter for 24 hrs which worked when the pool guys did a few wks back, but it doesn't really solve the problem of WHY it's getting cloudy in the 1st place. Thoughts??
