I'm nearing the end of a SLAM and wonder if a moderate amount of rain tonight could negatively impact the results of an OCLT that I plan to do tonight. Any thoughts are appreciated.
Thanks

Can Rain Effect My OCLT Results?

Keep the pumps running to circulate the water and use a draw stick to obtain water samples from 2-3 ft below the surface. Light rain should have minimal impact.

About $10 in PVC parts at the hardware store if you want to make a fancy one. Let’s me sample water 48” below the surface.

I use a 1” pvc pipe with a cap on it and a hole drilled just below the cap. Thumb goes over the hole as I put it in the water, thumb moves away to let air out and water in, thumb over hole to keep water in, pull out the tube and over my plastic container to collect water, move thumb and let water into cup. 
Y’all fancy! I use a piece of 1/2” or 3/4” pvc but I like the cap with a small hole drilled idea.

What do you consider to be the correct testing depth? And does it depend on the depth of the pool? Mine is only 5’ in the deep end.

Anything deeper than 18” is fine. You just want to avoid testing water near the surface as it can have slightly different chemical levels that the bulk of the pool water.

I used a piece of 2-foot-long 1/2" PVC with drilled caps on both ends. I sample from ~15" below surface. That's elbow depth for me. With an AGP, there's no benefit to using the draw stick except when the water is frigid, and usually I grab samples by hand at elbow depth.

I’m just lazy and don’t want to kneel down and get my arm wet to get a water sample.
