diy Skimmer?

[nano10]

Does anyone know where i can find plans to make a small cheap protien skimmer for a 10g tank? I seem to remember a thread a while back using a 20oz bottle and a airstone.

i have an air stone water bottle skimmer in my 20. my gallery has a drawing. i used a water bottle and a packing tube. but 2 water bottles would have worked the same...
