I have an IC 20 and screen logic. The IC 20 has the 20% light on but the screen logic is set to 5%. I assume the IC20 is controlling because my chlorine level is slowly creeping up despite daily swimming and some organic matter in the pool. But logically it seems like the screen logic, if set...

I have a 13000g plaster pool with a connected 800g hottub. The hottub is above the pool with a waterfall. I’ve noticed the hottub water level dropping more than seams reasonable due to evaporation. The tub has a cover, but it’s not totally covered due to the waterfall part. The cover has a...

My IC-20 stopped chlorinating within the last couple weeks. When I hold down the right arrow button all the lights do some sort of cycle but it doesn’t display the hours of usage. During run time, the salt and flow lights are on, but not the cell and not the sanitation lights. I’m not sure...

My “jelly jar” cracked due to ice. The replacement is $250 which is highway robbery. It doesn’t appear any different than the canisters I use for my water filter system and aquariums. Does anyone know an alternative to use? Tomorrow I plan to see if any of my canisters fit. Thanks!
