Having trouble maintaining FC with the high heat and direct sunlight, and basically adding 1-2 gal every other night. We're using BBB. At last check, my CYA was at 30. I added approx 2# of stabilizer (per calculator), but have not rechecked as I'm out of reagent. I'm assuming with little rain since addition, I should be around 40 or so on CYA. Either way, I doubt we're on the high end. My question relates to the Cl pucks. We do have an in-line chlorinator that we don't use since we use BBB. However, will it mess anything up if we use while we are away for a couple weeks in Aug? And if it's ok to use, will this really help much in keeping a decent level? We do have someone who will be staying here but will be in and out, so can probably count on a bleach addition every 4th day or so. We've managed to keep things crystal clear so far, so any suggestions on how to chlorinate when away will be appreciated!
