    Chlorine level dropped to nothing in 2 days

    Wth my Intex 18x48 2 days ago my chlorine level was perfect, today I tested and it was really low to the point of not registereing on my test kit. Will a clear solar cover cause this to lower that quickly ???? My PH is fine.

    Chlorine loss is normal daily. A cover will actually help not lose as much. Do you have stabilizer in the water?

    No stabilizer yet. Thinking about adding some bleach to bump it up. What do ya think.

    With no stabiliser your chlorine will not last long- you need to get stabiliser in ASAP. What test kit are you using?

    Stabilizer a must have, as for the the test kit it's just a cheap one not anything fancy. I always thought that if you had a SWG you didn't need all the extra stuff

    I'm going to put my system in boost mode and see I if I can get the chlorine back up

    Welcome to TFP

    Actually with a SWG you'd want to keep stabilizer (CYA) a little higher than with a non SWG pool as the CYA is sort of sunscreen for the chlorine and the SWG generates chlorine slowly.

    It also helps us if you update your signature with your pool info

    There is a lot of extra stuff that pool stores promote that we don't recommend as they are either unecessary or create further problems- needless to say they are also usually expensive. But there are still some things that are needed chlorine, stabiliser and acid are usually the 3 staples.

    You might want to consider ordering one of the recommended test kits while it might seem a little expensive to start with it will save you heaps in the end and keep you out of the pool store.

    andy I live in Michigan also and every spring I add stabilizer when I open the pool for summer.
    Otherwise the chlorine just disappears. I used hth stabilizer from walmart $8. 24 hours later numbers are spot on.

    Read up, then ask about anything you're not sure of. It's better to ask before putting something in you're not sure about. Do you know how to use http://www.troublefreepool.com/calc.html ?
