    Yes, but don't do anything about that until after the SLAM.

    Re: Calcium hardness

    It is true you are just under the minimum level for a non-SWG pool (250). As YS noted, not worth worrying about right now as maintaining your SLAM FC of "20" is most important. (Hint, hint ..... 20)

    Afterwards, it may not be earth-shattering if you have relatively hard water in your area and summer refills might increase that fairly quickly. In addition, your low CH is currently off-set by your pH and TA that are keeping the CSI elevated and plaster healthy on the CSI scale (Poolmath calculator) at about .28. So you're still in good shape right now. Happy SLAMMING!
