These power heads work perfect for my sponge filters in my Discus tanks! Only power heads I will buy.

Rated 5 out of 5 by Pickyone Quiet running
This pump runs quiet. I am happy with this pump. I started a new 20 Long tank, (30 X 12) and it seems to be just right with the undergravel filter. I also have the other Penquin models and they are quiet running and have been running for years.

Rated 5 out of 5 by vphelimaster reliable long lasting product
I have used these powerheads for some time. Couple it with the sponge filter and they make a good circulating jet for a reef tank; exactly where you need that extra circulation. The sponge makes a good home for various amphipods and copepods
