    Could low CH levels be causing cloudy water?

    Hi Folks,

    I've got my numbers and I had a question around CH levels. In the interest of full disclosure there are several problems with my pool. I've got a leak I can't locate and as a result am adding a lot of water, which means I'm loosing the treated water and diluting with freshwater. I fully understand that isn't ideal and will be digging in as the days go on.

    BUT, my water was beautiful the last few days and cloudy when i woke up. I tested early in the AM with the short test and it showed no chlorine. Added @2.5 gallons and let that filter for a few hours and did the long test. Numbers are as follows:
    FC: 7
    CC: .5
    TC: 7.5
    pH: 7.2
    T/A: 100
    CH: 100
    CYA: 0

    Now, I can't seem to keep CYA in the pool and I think that's because of the leak. As a result I am using a TON of chlorine because I'm constantly adding fresh water/ Vicious cycle that's costing lots of time and money.

    My hunch is the cloudiness is from not holding stabilizer and as a result not holding chlorine appropriately. Maybe this morning it was just all used up.

    But I've read pool school and I'm struggling to understand if that CH level a problem?

    Any thoughts would be greatly appreciated. I'm going to start taking some measurements and closing up the skimmers/returns tonight to help find the leak. Separate thread for that adventure. I have some pictures of our last attempt to find the leak.....

    I think your hunch is correct.

    You should test and add FC more often, but you also need to concentrate on finding your leak.

    It is alright for CH to be low for a while, but as soon as the leak is resolved you should raise CH back up.

    Thanks guys, glad I'm not going crazy. I added a floculent (Target 'Super Clarifier') and it helped clear the water up right away.

    Now on to the leak!
