This is my 2nd year with Autopilot SC-60 and I am concerned about the cell output level.
Hopefully this is enough information to offer advice. I have a 32K gallon IG pool.
1) Last year I installed the autopilot (i.e. no local support) and ran it on level 2 and it ran at 30% - 50% (depending on temp) and maintained FC at 4-6. I run the pump for 9 hours in daylight (for solar heating) and for 4 hours overnight.
2) This year, I am up to level 3 at 50% and only maintaining FC between 1-2 (same pump run time). (Also - I have shocked a couple times this season with bleach after large kid party - no problems occurring - just precautionary). Here are the other #'s today FC 1.0 CC 0 Alk 110 Ph 7.2 CYA ~60 Salt 3200 CAL 210. I'm also in the process of adding borates (hard to find large volume of borax). I'm planning on raising CYA slightly to 70. I've never seen any 'scaling' on the cell but I have cleaned it.
So why am I up 1 power level and down output this year, considering the # are roughly the same and runtime is the same. Is the cell going bad after 1 year (4 month usage)?
Any advice appreciated. - thanks,
