    How often to check cell??

    Is there a rule of thumb on when/how often to check the SWCG cell Does the amount of calcium in the water have an affect I would think it would, but I'm still learning. I've recently bumped my CH to 275 and plan on keeping it there due to getting a few cobalt stains. What other water factors would contribute to quicker scaling
    I did a search and couldn't find an answer.

    The chances of calcium scaling can be estimated by looking at the CSI. The higher your CSI, the more likely you are to have scaling. If you keep CSI slightly negative, scaling is unlikely. If you follow our recommended levels you don't normally need to worry about CSI at all, since the recommendations already take that into account. In a SWG cell adding borates lowers the chances of scaling by more than is indicated by the change in CSI, because borates reduce the amount of PH swing that occurs inside the cell.

    Now Jason, who else's recommendations would I follow Even before I added borates this year, my pH was generally always at 7.4-7.5.
    But, should I be checking it annually More,less

    Lynn I am not an expert but we only check ours when the "Inspect Cell" light on the panel comes on or we notice a decreased chlorine output. So to answer your question, we do not follow a regular schedule on that.

    Always check your cell at least once a year. If there have been calcium scaling problems in the past, or you have some other reason to suspect problems check more often.

    i'd say start with monthly, and if you find there is no build up - move to annually

    Hi Lynn,

    Your unit will remind you to check the cell every 3 months. With it's 'autoreverse' calcium shouldn't be able to gunk things up, but it's as easy as unscrewing the 2 unions and looking into the cell to see if you have cal or debris in the cell's blades
