The key from my experience is keeping the pool water aggressive enough (negative CSI) so that the scale deposit is soft enough to not accumulate on the plates. The reversed polarity feature of the cell will sluff off the soft buildup on the plates but the harder scale will not and eventually results in a low Amp (false low salt) shut down. I clean without acid and only use long zip ties and a water jet. My cell has many plates very close together so its tedious but only takes 45 minutes total. Frequent fill water high in TA requires a close eye on pH and TA. Filling your pool mid summer with high TA source water is your issue. Once your pool TA is down to 50-60 ppm you can counter the fill water additions by anticipating acid demand at peak evaporation months and minimize the cell maintenance needed.
