ya but that is the result of polution or an algae bloom in the water, in a normal stream/river, ect you get bubbles but they disapate imeadiatly, so no benifit. in normal fresh water there is no way to get foam with out adding something.
now I did read where you could buy an aditive to your tank water which increases the surface tension which makes skimming possible, but I can't remember what it was called or if there was any effects from long term usage.
