Penguin Powerhead Replacement Sponge 3 pk
These power heads work perfect for my sponge filters in my Discus tanks! Only power heads I will buy.

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.

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

Dependable Power Head
I've been using the Penguin 550 Powerheads for about 17 years. I don't recall one ever failing me but I don't keep up with cleaning the tank very well and the top of the head will get a hard scale after a couple years and I'll replace the heads with clean ones when I do a thorough cleaning of the tank. I have used other brands of powerhead and some have failed, and the output is not as flexible as the 550.
