Alternate Pool Sanitzer?

[Pool Newbie]

I will be installing an indoor, small (9 x 12 foot) exercise pool in a few weeks. Because chemistry is very hard for me, and as the only person who will be using (most of the time) and caring for the pool, I was thinking of using a UV & chlorine system (about 0.5 PPM the info says?). Does anyone have any strong thoughts about this type of system? I have a SLIGHT allergy to chlorine, and after observing some fellow long term swimmers at the YMCA, I noticed a lot have sinus issues - I know not necessarily the fault of chlorine, but one fellow who swims EVERYWHERE (his own pool in summer) says the problems are from it and he's not quick to poke accusations. Thanks in advance.
