Thanks. Would be great if I could see the darn stuff - then at least I could check to make sure I'm making progress!
Maybe I'm overthinking this (or clutching at straws) but my FC was 19 at 6am. Added 1 gal 10% which per Pool Math raises FC by 6.2. Tested at 11:30 and my FC was 25, indicating no loss. So in 5 hrs, no FC loss, whereas in 9 hrs overnight, lost 4 ppm. Strange?
