i have my autopilot going since the water has been about 55 and now it's warm enough that the autopilot temp compensation is allowing higher chlorine. and i started running my heater today as well (went from 62f to 76f during the day. knowing that once the water warmed up, the autopilot would produce more chlorine, i had turned it down to about the 3rd dot from bottom last night so i assumed to about 30% of the time active. today i came home, and everything's running fine except i notice my autopilot has been running 100% activity for not sure how much of the day, but let's say for 4 or 5 hours anyway. maybe longer..the pool was 65 when i got up and was 76 when i got home so don't know when it was able to kick up to 100% but it did. and then i took off my solar cover to clean the pool and tons of bubbles! i did my cleaning, turned on the skimmer valve only to speed up the clearing of the bubbles..that worked and got rid of them (and meanwhile, i had turned the autopilot off as while all chem levels are fine with a taylor test kit, the chlorine was through the roof. at about 15 and you could easily smell the chlorine..) so, i left it to clean the bubbles, hopefully and it did..hooray..no due to a leak or the furnace or filter or anything..i turned on the autopilot again but turned it down to like 1 dot level..had supper, came out half an hour later (heater was still running and was up to 77f now) and the autopilot had adjusted up to the 2nd dot by itself..ok, the temp comp is still working as the pool's getting warmer. but, i noticed more bubbles starting to develop! so, to test this, i turned the autopilot off as i could see the output into my water like a fine white cloud from the returns. as soon as i turned the autopilot off, the water out of returns was clear again within 10 seconds for the nearest return...the furthest return, about 30 secs which makes sense. so, i've determined it's the autopilot..does this sound normal? it was only in service for 2 months last season after i got it and i don't recall bubbles..then again, i ran it very very low..never as high as it was going. maybe 2 dots, 3 dots up in the high heat of summer (it was installed in july and ran to september and the water was already in low 70s when i started to run it) airtemp for reference at the hottest point today was about 75 and again, pool temp was 75, 76 this afternoon when i noticed this.

meanwhile, i think i should just turn off the autopilot and let the chlorine level slowly go down ( i have a solar cover on most of the day and cya level of 60 so....) before bothering to turn the autopilot on again.

it's definitely different circumstances now temp wise, and output wise currently, than it was when i installed last year. i'm thinking next year, start off far more conservatively on the output level than i did this year. i use chlorine beach to shock the pool at the start of the season, not the autopilot. ps- the salt level is at 3300-3500.

any thoughts appreciated
