My SWCG seems to need to be on a higher percent this year to keep the pool at the same chlorine level as last year (7). I know the pool is clean it is not using any more chlorine, the SWG is just making less. Do SWCGs lose efficiency as they age? This is just the 3rd full year with it running. Beginning of this season the plates were clean. I have never cleaned them the CSI takes care of that. Should I be cleaning them anyway? The first 2 years it was keeping FC at 7 at about 53%. This year I am dialing it in and at 60% it is not keeping up (just checked it was at 5). I bumped it to 65% which I think will be ok. Also I think my CYA is a bit higher this year than usual. Last year I ran it around 60 and this year I got it up to 70 so thinking it should be using less chlorine.
