    Chlorine levels go down close to zero overnight.

    I added 70oz of liquid chlorine last night. Cheap test showed both FC and CC at ~4.0. This morning they are both still at ~4.0. Just wondering, could there be a problem with the SWG? It’s a Jandy Truclear 11k, 2 years old. Thank you!

    Chlorine levels go down close to zero overnight.

    My test kit arrives on Monday. I don't have a reliable way of testing CYA right now. Pool supply store said 70 for the stabilizer but I see 30 (maybe less) with the hard-to-read test strips. Testing with my cheap drop test kit in the afternoon, after the SWG has been running for 9 hrs at 70%, I...

    I just ordered TF-100 test kit today. I'll report back once I have the test results. My pool is 11,000 gallons. I have a Jandy TruClear Saltwater Chlorinator. Not sure about the "size", but the brochure says: "produces 18 grams of chlorine for pools up to 35,000 gallons.". I have it at 70%...

    Battery stain

    Ok, i removed it after about 40min. It worked OK. Stain is almost gone. I can still see it but maybe because I know it’s there. Thanks!

By the time I discovered what had happened and found the battery (at the bottom) the battery had created a stain on the bottom...
