I just filled my brand new pool. I posted my #s in another thread (CYA looked kind of low, TA was high, the rest was OK), but this question isn't really related. When I look down at my water during the day, it's crystal clear. However, if I look down at it at night with the light on, I see lots of stuff floating around (or maybe little bubbles?). I tried to capture it in a pic, but it's hard to capture correctly. Is this normal?
Note that this was taken after sweeping. I swept with the filter and cleaner running, then let everything settle for ~5-10min before snapping the pic.
