Penn Plax Small World Replacement Filter Cartridge (3 Packages / each Package Contains 2 Filters / 6 Total)

Love it

Easy to use. Mine is in a patio mini goldfish/minnow pond. Just powerful enough to oxygenate the water and filter a bit, along with water changes and vacuuming. substrate.

I needed a replacement filter for the Penn-Plax BettaWorld filter I use in my 2.5 gal baby fish tank. These filters offered the perfect replacement option. Snap in and go! My tiny fish are safe and their water stays clean.

The first set of these I ordered looked exactly the same as any other new package. The second time they were all covered in black (charcoal?) dust. I rinse them off as best I can before using them but I'm not sure how it effects functionality. If I order again and receive old stock I will return them and stop ordering from this listing.

Great for small tanks. Easy to install Clicks into holder.

So far the best solution we've found for a quiet, passive filtration setup in our 5-gal Betta tank. Filter good for a month.

I have been using them, for years. Easy to remove, change and clean. Lasts for about a month.

I love everything about these. I couldnt say enough good things most important is the design it has. Easy to clean, throw the old filter away and install a new one. I messed my tank up really bad one night within one and a half I had literally sparkling water. Again it's great!!!!!

Easy to use, just rinse out of the package and snap in.

This might be an expensive way of filtering your tank opposed to washing filters. I’d choose this method all day long. The gaps between tank cleans are twice as long as they used to be.
