These heavy duty filters provide both mechanical and biological filtration. 1" diameter lift tubes move more water than other sponge filter and can be used with a powerhead or airstone. Raised sponge eliminates dead space under filter. Heavy base keeps sponge where you want it.

Great for goldfish
 
 
Pros:
easy to clean, produce little turbulence, stay put
Cons:
none
Love these cheap, effective filters. I have one large fantail goldfish in a 29 g with an Aquaclear 30, Aquaclear 50 and this sponge filter all going. Does a great job at collecting debris and is super easy to clean...just remove sponge and squeeze it out repeatedly in a bucket of tank water. No cons that I can even think of!

Great filter
 
 
Pros:
Multiple applications , easy to maintain , great filtration.
Cons:
Bulky but who cares..
I use two of the biggest models in my 58g African Cichlid tank , and they keep the water crystal clear and ammonia free. I attach a bubble stone inside rather than a straight air line hook up , and it works awesome. If you really want the best , mount a power head to the top , works beautifully,and aggressively at removing waste and particles from the water column.

Amazingly easy to use product
 
 
Pros:
easy cleaning and long life, plus low price!
Cons:
takes up space.
I have used this as both a pre filter to a HOB as well as a a stand alone filter for a betta tank. I have thus far used the up to 20 model in a 20 gallon tank as a pre filter for a 30-60 gallon tetra HOB filter. it reduced the flow just as i wanted and kept the water crystal clear. In a 10 gallon tank have been using an up to 20 model which is a little tall unless you make some slight adjustments. I would suggest a pair of smaller ones for a smaller tank if your trying to hide it. I also suggest using them with a small air stone to improve the vacuum function with an air pump. also the larger the air pump the more water it will move. betta fish love these filters!

No more baby fish sucked up!
 
 
Pros:
Keeps baby fish from being sucked into pump
Cons:
These are great baby fish savers! Also keep debris from getting into your impeller, etc. You can use them alone or as a pre-filter.

Best Supplmental Filter
 
 
Pros:
Durable, Easy To Clean, Quiet, Effective
Cons:
These inexpensive filters are a good investment for any aquarist. Excellent bio-filtration. for best performance, add an extra line of air tubing at bottom end of bullseye for a more powerful vacuum.
