So, I need to do an OCLT. I HATE having to get up before sunrise!! Did I mention I HATE having to get up that early!? 
If the point is to see if FC drops in the absence of UV light, it got me thinking: would it work to take a pool water sample in a water bottle, place it in a dark place (a closet perhaps) for about 10 hours, then test it to see if FC was lost? This way one could do an OCLT on their preferred schedule.
Any reason this wouldn’t work?
