SWG and OTO testing

[AK-]

Before buying a SWG I always found the chlorine test on the OTO to be utterly useless. Now with an SWG I found it to be really useful. What a surprise.

Back when I was using LC I was running my pool hot (never believe the target). When your low FC threshold is 6 and your target is 9 the OTO results are meaningless.
Now with a SWG I’m my personal target is 6 (since I only run my single speed crappy pump 12h a day) I find that testing with OTO every other day is enough to keep my FC in check. I still test with FAS/DPD every week (well at least last couple weeks).

On an unrelated side question. I noticed more chlorine smell (light smell, not CC smell) since I switch from LC to SWG. I believe it to a small portion of the chlorine gas escaping the water before becoming hypochlorous acid. Anyone else noticed something like that?

I've not noticed the smell you are referring to, but I can understand the increased value of the OTO.

No smell noticed once the solar cover died and I didn't replace it.

Run hot for a week like you used to and report back.

I did that and no difference. It is a faint smell different than the strong CC smell when the solar cover comes off… In smell matters I’m like a sniffing dog.
BTW, the faint chlorine smell is only noticeable on the side of the pool my return jet is pointing to.
