Great Filter for small tanks
Date: April 12, 2009
"I picked up a PennPlax Small World filter/aerator to use as a second filter in my 5 gallon tank. I try to keep two filters running to minimize tank shock when changing the filter material. The one feature that initially annoyed me with the small world units was the fact that I had no way to remove the carbon when I needed to add meds for a new fish. But, after looking at the situation, I realized that I could pop out a few of the plastic strips at the top of the unit and the carbon could be poured out without damaging the rest of the filtration unit. When I'm done with the meds, I'll pop in a new unit, and it will be good as new. Great price - great solution - great size."

"I have to agree, that this is a awsome item for the small tank . But trying to get replacements ,,, it ain't easy. You'd think with such a great product they would keep more handy."

Great set up for a Betta Tank
Date: May 4, 2008
"I have used this product in a number of my tanks 5 gallons and under,for Betta's,Aquatic frogs,etc.
For as little as the actual product is,it really does keep the tanks in good condition.The best part about this set up is,
a) Easy to find
b)cost friendly
c)easy to replace the filter cartridges.Penn Plex sells a pair of these together,and when I see them ,I grab a few sets.
Their slim measurements make them great for the smaller tank set-ups.

never fails
Date: May 4, 2008
"I have a large tank and any time I need to put sick or weak fish in a quarantine tank, which is almost never, these filters help me the most. They never disappoint me and the fish love them because they are submersible and there is no need for an aerator."

Great Product
Date: February 14, 2008
"I am currently using this filter in my 2.5 gallon aquarium. It works really well and you can see that it's working since you'll see the dirt getting trapped on it's filter media. I would recommend this product"

Good for Goldfish!
Date: February 3, 2008
"I have this filter system for my goldfish and it works great. The filter only needs to be changed every month or so just like any other water filter."
