Fighting a swamp!:O(

Ok, You need to use the teflon or silicone lubricant recommended for rubber O-rings. Petroleum products destroy the rubber.

I am fighting a bloom as well, but because my liner is old and I don't care about bleaching, I've got my FC level a lot higher than the 15ppm recommended.
I wouldn't worry much about going over by a bit, even to 24ppm, because it will come down fairly quickly and it's worse to be UNDER 15ppm than over.
It's not certain how much over the recommended shock level you can go, or for how long, before you risk bleaching the liner.

Thanks BigDave , got all Vaseline off and ended up having to shave a tiny bit at the whole to make it bevel(?) a bit to get it to slip down. It was the recommended unicel C-5315 through this Amazon site and it is working perfect now, still real snug. Everything seems to be working and water is clear. CarlD, Have FC at 5 this morning. Got double extra drops for my Taylor kit so I can be more exact. I'm guessing I'm not too good of a guesser with the OTO so don't want to risk the guessing game again. :O)

OK, using the FAS-DPD test, don't use the 25ml level--it just wastes your 0871 reagent. Use either the 10ml line (2 drops = 1ppm of FC) or, if FC is very high, use the 5ml line and 1 drop =1ppm of FC.
