I hope Chem Geek happens by, but this is also for anyone
Converted to SWG a couple weeks ago. My CYA is high. It was 140 and I got it down to 130 before converting. It should keep falling.
In any event, Chem Geek's math showed I'd need about 20% run time on my T-15. I'm not even CLOSE to that and not losing anything. I'm running it at 50% for only 5 hours a day. I'm getting FC of 14 in the afternoon after the pumps have stopped, and 13 in the morning before they start. Even with that CYA, AND having an enclosure, shouldn't I be losing more? It's not an OCLT, as it includes all loss from 1 PM to 8 AM the following morning and losing 1 PPM at the most.
On a side note, I keep reading 13-14, pool guy always reads 7-7.5 when he's here. NO idea what kind of test kit he's using, but I'm disturbed at the drastic difference. Well, other than even his shows it as being stable.
Just curious if my enclosure could be making that big of a difference, combined with the high CYA.
