Just added pH up and pool got cloudy

Well, the cloudiness could be due to something trying to grow in the pool water. Your TC is 3, but FC is 1, so that means the CC is 2....(TC=FC+CC). If those numbers are indeed correct, you'll need to bring your chlorine up to shock values and hold there until the CC is 0. Use Bens' best guess guide to determine your shock values based on the CYA level.

Are you using bleach or pucks for chlorinating? Bleach sometimes increases pH, whereas pucks (which are very acidic) will decrease pH.

Good luck.

My pool clouded as I poured the dilute pH up into the pool. This wasn't algae growing!

My CH is 120 (160 before pool draining). Thats low I know, but I just drained the pool earlier this week to get the CYA down from 135. I also had phospahates greater ~2500. Treated the pool yesterday and brought the phosphates down to ~100.

I thought there might be residual Phos-X in the pool that may have contributed to the cloudiness but didn't mention it since I could still detect some phosphates. I used 12 oz in am (tested PO4 ~1000 ppb) then went with 20 oz to finish treatment at noon. Dosage for decreasing PO4 1000 ppb per bottle directions was 32 oz, and I used just 20 oz in the second treatment. Cloudiness was minor and pool was crystal clear before I added the pH up.

My problem, which I thought I treated correctly was algae.
1. Lowere CYA by draining 1/3 of the pool (20,000 G)
2. FIlled pooled, add alkalinity to ~120 (test strip)
3. pH was 7.4, TC 3 (OTO), FC ~1 (test strip)

This am pool ph was 6.8-7.0 by OTO and test strip, so I added 2 lbs pH up.

So there' sthe complete picture.

[Bleach=Chlorine?]

You need to keep the Cl level up to 15ppm and keep it there until you have zero CC. I would stop using all that other junk and also get a good test kit.

Bill,

The other additives may well have contributed to the cloudiness.

My memory is vague but it seems like I remember something that pH up (which I think is soda ash) can contribute cloudiness to a pool under certain conditions. I think I remember also that it is temporary. (Wow! Talk about wild guesses!)

Waterbear, get in here and straighten this out!

Well, there's your problem. You said test strip.
