    Boost from SWG and now PH is low?

    Guys, need a bit of help here. My chlorine and calcium levels were low, so Sunday i added calcium as per instructed, then i pressed the Boost button on Monday evening on my Digital Autopilot. When i got home today, the chlorine and calcium levels seemed fine, but now the PH is really low.

    Is this normal and what should i do next?

    Thanks!

    Usually the PH goes up when you are using a SWG, but there are a couple of things that might cause the PH to go down.

    We could give you much more specific help if you posted a full set of water test results. Terms like "low" and "really low" don't tell us anything useful.

    Boost button on SWG and PH being low are unrelated events.
    Adding calcium chloride would have minimal effect on PH.
    Accurate water analysis is the only reliable way to know what is causing the PH to drop.
    Anything else would be just a guess.

    I just checked the levels again and everything is fine. Sorry guys, my bad! I think i must have put yellow drops in both sides of the water tester. lol

    Makes sense now cause my ph was perfect a few days ago!

    Thanks anyway!
