You can add a waterbed heater for about $15 off ebay to keep it from freezing.

Density depends on the fish and how big they are. I only deal with tilapia. You could probably do 50 tilapia in a system like that.

I do not think I have room for the pool so I was think 1-3 stock tanks maybe add to them as needed.

Is there a difference in Submersible pond pump and just a regular sumersible pump?

I want to make one of these filters do you still have extra beads or know where I can get some?

Can you use a filter like this with an aquarium?

You mentioned that this sits in your sump, can you explain the sump more or is there a separate thread with you sump?

What is considered pool base?

$100 for plumbing, is this just the materials like the PVC etc.?
