Just added pH up and pool got cloudy

[waterbear]

soda ash can cause clouding of the pool because it raises the TA along with the pH. the higher TA and pH can cause the calcium to precipiptate and cloud the water

Mr. Bill:

I KNOW it's tough to absorb everything. Sometimes, when the pool is cloudy and we are panicking, it's tough to remember that the MOST important thing is to keep our water sanitary.

IF your strips are accurate, a TC of 3 and an FC of 1 means you have a CC of 2--and that ain't good! It means you are fighting some kind of organic, probably algae about to start. If you don't fix that, other problems will seem minor. Since your CYA is 50 (according to the strip) your FC level should ALWAYS be between 3 and 6--preferably 5 or 6. Shock by raising chlorine to 15.

Fix that first--A pH of 7.0 is low but livable--and chlorine is more effective at lower pH levels. A pH of 7.6 is fine, too.

Once the chlorine is fixed and your pool is sanitary, you can concentrate on the other issues. Frequently, fixing the chlorine clears up other issues.

Pool was just alittle cloudy this morning with a with precipitate in some spots. At this point my pool is looking great. I had shocked the pool twice @ 10-15 ppm earlier this week. I am testing with OTO drops for TC and test strip for FC. I ordered the PS234 Test kit on Tuesday. I don't want to superchlorinate again until I have more reliable TC, FC test results.

I mentioned earlier that I'm trying to lower my CYA by draining the pool. Did about 30-40% three days ago and another 6-8 inches this am.

Added one LB bag of CAHypochloride and tests are:

TC 3++ OTO drops
FC ~3-5 Test strip
pH 7.6 OTO & Test strip
ALK ~120 Test strip
CYA ~50 Test strip
CH ~120 Test strip
Can't wait till I get the new test kits!
