Hamburg-Matten Filtration system.

I was considering toying with this design.. and might still do so.. A really interesting concept that's swept the Euro fish keeping community:



here's the article from which I high-jacked the pics from.. WARNING: .. it can become pretty entangled in the weeds! http://www.janrigter.nl/mattenfilter/

That's so funny. That's what I was planning on doing for the two 20H that I am getting ready to set up. I was looking on youtube this weekend and found quite a few videos about HMF. I think i'm going to give it a try. It looks like a much more efficient design than regular sponge filters. Do you have any idea where to find the foam? Let me know how it goes.

A guy up here is talking about getting foam from a cheaper source. If I can get extra, I will post here - may be able to have it at the PVAS April Auction. This guy has his own angel hatchery, so I am confident his is a safe source.

I will warn you that not all open cell foam is the same. I have a bunch of speaker foam that will not work because it apparently is treated with fire retardant chemicals - killed a few test shrimp figuring that out.
