I use these as filters, dividers, extra media....excellent foam at a reasonable price
Very pleased with my Matten Filters on both my 20 gallon long Neocardina tanks.
These foam filters are great. I have numerous 75 gallon tanks using these for hatching and rearing fry. Nothing beats it. Highly recommended.
I love using these filters,they hold alot of good bateria and keep my 75 gallon planted tank very clean.I also cut small slits in it to attach anubias plants to it .
This was my second matten filter from Angels plus. Really like the fit and function of these filters.Using a pump to pull water through and then pumping it through hoses to far side of the 55 gallon tank for a hillstream tank.
