So, thanks to the chemistry wizards here, I'm in the middle of dumping a good amount of pool water, and as the level drops, I noticed that my fiber optic lenses were pretty cloudy..not surprising after 10+ years of chemical is the pool wall light housing: ... s_id=19386

Don't know if it's realisistic for me to get two or three of these housings to install before my water refill covers them up again...but curious if any one has replaced these lenses before and if I dare try to do it myself?
