Hamburg Mattenfilter

[fredyx]

I've used it for breeding and rising fries is a perfect filter for that. Mine was "moved" by a powerhead and nitrites and ammonia were always under control.
Problems this filter has:
-Need more time to "mature" than cannister filters.
-It has no mechanical filtration and gets quite dirty, so aesteticaly is a bad system, not intended for display tanks.
-It needs more room in the aquarium than other filters.
-If you need to medicate against bacteria you will kill the beneficial ones in the foam. If you leave it in the tank by the antibiotic, if you take it out of the tank won't have water circulation and will die anyway.

One good use of it is to make divisions in a big tank: You put the foam as divider and the pump or air pipe taking the water from one side to the other. By means of it you get good filtration and you divide the tank at the same time.

I have used them when I was running my Discus hatchery back in Chicago. I had no problem with them. I had one for every grow-out tank, which were always way over-stocked. Aside from the biological benefit, it was nice to hide the heater behind it and keep it out of sight. Cleaning them was a pain, tho I did not have to do that often. It was a small trade-off. As said, they make great dividers as well. All in all, I really liked them, and would not hesitate to put them back in use if needed...Bill

My disclaimer....I have HMF filters in some of my tanks and have found Dr. Tanner to be readily accessible and helpful.
