I do not know if this is appropriate to post, but a Fish Hatchery in Lima, OH is selling live fish and the PVC Ribbon Bio-Fill Material on ebay for really low prices. The PVC Ribbon would give one an SSA of about 1800 square feet in a 55 gallon drum. And, this stuff works pretty well in water applications >65F. The water needs to supply the O2 as with any submerged bio-filter, and as with any bio-filter, one needs a decent solids filter in front.
Search "Aquaculture".
This stuff will work much better than deer netting, and seriously cut your electric costs.
I was all set to order when I found out it was only 8 dollars a cubic foot but then they wanted 80 bucks shipping on 5 cu ft... Oh well it was a thought. If I could find it for 10 or 15 a cubic foot shipped to my door, I would try it.
I been thinking of adding additional deer nets to my filters too. I don't think that's going to double the filtering capacity if I double the netting. But it's got to help some.
