Little movie from my scrubber, still in heavy DIY mode. 2 clear tubes glued to a flat bottom. Inner tube is dry and contains light bulb. Between inner and outer tube a water/air mixture is pumped in around a nylon mesh.

Hope it works, up and running for 32 hours now, and I think I see some green already.

Excellent!

I had the very same idea a while back but never built it.

Hope it works well for you.

Design flaws: it floats ;)

I need someting heavy to hold it down in the water.

Had issues with my main return pump (it sparked under water!), sump has been off system for amout a week now. Just got a new pump, so i'll start fresh over.
