5 gallon bucket for Biofilter?

putting in a 55 gallon below surface is not an option for me. I think
I'll try a 30 gallon rubbermaid container for an above ground filter.
I like the pot scrubbers idea, but I also heard about using cotton
batting from the local walmart. Any other idea's?

them at Big Lots for 99 cents for a bag of 9 I think. I would say
that
a five gallon bucket is probably big enough. Do you have plants in
your pond? I have a lot of plants (water hyacinth, water lettuce,
irises, horsetail, etc) in a pond that is a little smaller than
yours.
I think the plants do most of the work. My filter is a mesh plant
basket containing scrubbers, and my pump. I cut up a plastic coke
bottle to maintain a clear path to the pump inlet. I topped the
basket
with plastic gardening fabric.
