Filter: Whole-tank Foam Filter (Hamburg Matten Filter)

1000 uses

I use these as filters, dividers, extra media....excellent foam at a reasonable price

Excellent filters

Very pleased with my Matten Filters on both my 20 gallon long Neocardina tanks.

Whole Tank Filters

These foam filters are great. I have numerous 75 gallon tanks using these for hatching and rearing fry. Nothing beats it. Highly recommended.
