Thanks to TFP I seem to have successfully killed whatever was lingering in my water. It is now crystal clear, very little CC and almost zero OCLT. So for the first time in just over 2 season I have clean water (fought a battle all last season with chlorine levels - now I understand why and believe it's solved) and I'm not sure what I should expect from my SWG.
I run my pump/filter 24/7 and run the SWG 24/7. Should I see an increase in FC overnight with the SWG running or should it just be maintaining FC levels overnight and throughout the day?
