Show Me Your Sump in a Tub.

[BaliReefBox]

Guys for my new build I am thinking of having a large HDPE tub as the sump. I plan filling it with live rock and letting this be the "filter". For those that have this setup care to share a pic of what you have done...
Thinking along these lines or a large beer cooler/esky...
Do you light the sump on the live rocks?
PLease let me know and thanks
