Light green water

Go to just above whatever the lowest reading on your pH test is.

You have to remember, that if 7.0 is the lowest reading on your kit, a reading of 7.0 does NOT mean that your pH is 7.0. It means that it is 7.0 . . . OR BELOW! It could be 6.8, which wouldn't hurt anything in your case. But it could mean 5.8, which would damage your liner fairly quickly!

The lowest on mine is 6.8 so I will get it to 7.0. I ordered the 2 bottles of that metal calcium stuff. It says it'll be here by the 29th or 31st. So I want to leave the pump running 24/7 until then. I know I need to scrub and vacuum daily also, which I do. Do I want to add any clarifies or flocs? Or just keep filtering? I appreciate your help so much. I have learned a lot from reading posts in the forums and am learning more now

No clarifiers or flocs. We rarely advise adding those on anybody's pool. Just keep filtering.

[Huskerdee]

Thank you, no floc or clarifier!

Hi, do not be offended but too many pool owners make it more complicated than it is. I would follow Ben's advice and keep it simple.

I had the PH down to 7 but it keeps creeping back up. How can I keep it down w/o using acid daily? I am suppose to have the metal chemical tomorrow and will add that. That won't help stabilize my PH though, will it? My chlorine holds steady and I have had to add bleach as it' really high.

Do you have some sort of aeration going on in the pool? Waterfall, spa, etc? Aeration will raise the pH. Also, if you can turn your return eyes downward so they're not rippling the top of the water, that will help. What is the pH of your fill water, and what is your TA?

I do not have any aeration or fountains. I did turn the return up because I read in here somewhere that will help lower the alkalinity. My alkalinity was 240 but is down to 190 after 4 gallons of acid. Coming out of the tap my PH right around 7.8.

[aylad]

When you lower alk, the method is to add acid until the pH drops to 7.0 (the TA drops with it), and then turn the returns upward to ripple the water in order to raise the pH again without raising the TA. It does lower the alk, but it also raises pH. Dropping the TA lower should help stabilize your pH, unless you're using stabilized chlorine--if you can get it to the 90-100 range that would be great. However, I will tell you from experience that if your fill water has a pH of 7.8, it's a losing battle to try to fight it, because the pool will want to stay around 7.8. That's what the pH from my tap is, and my pool wants to be at 7.8 no matter what I do, so I just don't fight it. Makes life easier
