Not saying conclusively BUT....
I've been chasing a FC demand issue that maintaining shock levels for days wasn't taming. Have been losing about 6ppm FC per night while trying to achieve the OCLT.
Pool is sparkling as if there is almost no water in it. No CC or less than .5. Still consuming with no end in sight.
Head scratcher here that has me looking for what am I missing. I've never had the light out since we bought the house a few years back. It has 2 bulbs in it and one is burnt out. Decided to take a looksee...
Well without further delay.. Here's what I came up with.
Could this finally be the end?? Well I have some cleaning up to do here. I'll report back to see if we begin to make headway
A word of advice here is that if you are chasing something that isn't making sense maybe check the light niche. I must say this was an absolutely disgusting find.
