How do I deal with nasty surprise behind pool light?

Sustained shock level should do the trick!

Thanks Ben.

How long should I sustain shock level? Just until CL holds overnight like I did for spring opening?

What's your CYA level?

====================

Let me answer differently -- dose at 20 - 25 % of your CYA level, and hold it above 15% for 3 days.
