    Pool return line air?

    I have two valves on the return side for the pool. One is for bubblers and other is the jets around the pool. When I open the one for the jets around the pool all the way, my pump makes noise like air is in the lines they are visible in the pool. Bubbler only does not do it. Hot tub does not do it.

    Scale tec and chlorine level

    The directions say lower chlorine to 1 - 3. The pool is about 15, I shocked before slowing it all down for winter. Salt gen is turned off. Might be awhile before it drops to a level that low. Is it that important to wait until it’s that low…? Thanks

We brushed 3x a day and ran filter system and just keep going. The pool 8 months old, plaster. I test and keep water around...

    Added borax and MA

    I added borax and MA. Next morning testing shows it’s killed my chlorine and CYA. My question is did it kill the reading or actually the levels? Thanks.
