Sorry Eli I should have been more clear, this is what I am running:
The Rubbermaid Brute is just a garbage can. As you can see I've stacked my rock away from my heater. I would like to stack the rock all around my pump and just set the heater on top of the rock, is it safe to do that?
So no GFO eh....but wouldn't running GFO encourage the rock to leech out the phosphates quicker?
Thanks,
Ron
