Whats up with my cleaner shrimp?

[Reef Pilot]

I have one of those multi meters, so thought I would test my tanks, just in case. And to my surprise, my refugium tank has stray voltage. The needle moved quite a bit.

Turns out it is my T8 light fixture sitting on top of my lexan tank cover. There is a bit of salt creep around the fixture, so will have to see what I need to do to fix the problem. Still surprised how that gets into the water. But when I shut it off, the stray voltage is gone, so that is definitely the source.

Thank goodness, my display tank and sump checked out OK. I have a lot of pumps and electrical devices in and around them.

Glad I read this thread, or never would have thought of checking.

Canreef rocks!
