Yes, I did want to reply, and didn’t lose the link, but it was kind of you ask in case. Thanks, also for your earlier response and the links.

The above ground exercise pool I’m installing indoors will allow only a little over 5’ head room above the water (good thing I’m short! ). An HVAC person has looked at it for venting and moisture control. I’m hoping that what he comes up with should also be adequate for chlorine vapors as well, but wouldn’t have thought of it without your comments (thanks again!), and my father says the wiring should be insulated and in tubing, so hopefully that shouldn’t be concern either?

With the UV, and because the pool will mainly be used by me, and on occasion some family members, and even less frequently by friends, does 0.5 ppm sound adequate?

As for other choices than the chlorine ….

Is Bromine a GOOD option? I know you said not in sunlight, & since UV is a kind of replacement for sunlight, I’m assuming it wouldn’t be useful with UV either? Do you support Bromine here at the forum?

I know *you* use UV + peroxide + polyquat, and I think you said high maintenance, which makes me reluctant to go that route.

Bacquacil – I’d rather take it intravenously. After reading about the water mold, I would prefer to avoid like the plague. Also, since I’ll be pumping city water into my pool, I’m reluctant to replace it every 6 mos., even tho that’s what the Ipool recommends.

Nature2 – Apparently for my small pool, this is an option, but since it too needs a small amount of chlorine, I think I’ll stick with the UV and chlorine.

Did I miss anything?
