Joe M: The removable cartridge is filled with a solid sponge filter media, charcoal and zeolite. The foam catches free floating debris, the charcoal absorbs odors/trace contaminants and the zeolite reduces ammonia, which is most deadly to aquatic life. The charcoal and zeolite last for about 3 to 4 weeks, at which point, you are instructed to replace with a new cartridge. WRONG!!!! This is because the old sponge media now houses beneficial bacteria that convert the remaining ammonia to Nitrite (still pretty deadly), and then to Nitrate (the least deadly, which can easily be controlled by water changes). In other words, the naturally occuring NITROGEN CYCLE that all knowledgeable in the hobby follow is cut out by new cartridges. SO IN ORDER TO MAKE IT WORK RIGHT, YOU NEED TO GENTLY CUT AWAY THE BOTTOM OF THE ORIGINAL SPENT CARTRIDGE; THEN GENTLY REMOVE THE SPONGE AND SQUEEZE OUT CLEAN IN A BOWL OF TANK WATER IN ORDER TO MAINTAIN THE BENEFICIAL BACTERIA COLONY; THEN DUMP OUT THE OLD CHARCOAL/ZEOLITE AND REPLACE WITH YOUR OWN, BEFORE SQUEEZING THE ORIGINAL SPONGE BACK INTO THE ORIGINAL CARTRIDGE. Changing to new cartridges might be great for profits, but it defeats the purpose of the...

Susan Gove: This filter is the perfect size for my 2-gallon fish tank. I attached the air pump with the back flow connector because it would be sitting lower than the filter. All I am getting are a few bubbles through the filter, not what I expected. Also, does anyone have any tips on how to keep the tubing connected to the items on it? I just can’t seem to get the tubing on far enough.

Rebekahs Saunders: These are the right replacements for the filter I have. Unfortunately it wasn’t the cartridge that needed changing-it’s just broken!

taburn: I bought this filter because I didn’t want a big sponge eyesore in my 5g tank taking up a lot of space. This little air driven filter was the perfect solution. It works well and was very easy to install. The one downside is the media is not removable. You have to buy the replacement filter cartridge so any bio filter in your filter is lost. Probably great for beginner fish keepers who are not in tune to the nitrogen cycle, though. I would like to see a latched door at the bottom so I could replace the chemical media and just squeeze out the sponge and put right back in. Some reviewers said they just cut out the bottom to do this. Regardless, great little filter!

MattVSMattVS: I bought this filter for a 5 gallon API PanaView aquarium that houses one betta, Mr. Buddy. I purchased the entire kit.

Mr. Buddy has been living the good life in a filter-less thank that has had weekly water changes for three years, so he is not super happy with this recent change to his home, but we made deal. At night while he sleeps on his betta leaf near the surface, I turn the pump way down. During the day while he is awake, I keep it at a wee bit past medium flow.

Pros:
- It works! At first it was moving some of debris around, but by morning it had cleared.
- Pump isn't super loud, imo.
- Media isn't crazy expensive and if your crafty, you can make your own in the provided media container.
- You can control the bubble flow. It does move the surface water, but by the time it gets to the far end where his leaf/bed are, it isn't too rough.
- I tested ammonia and nitrates just to make sure the moving debris didn't cause a spike. It didn't. Everything is still 0ppm.

Cons:
- Lord give me strength. Why is there JUST enough air line tubing?! It's not safe since the tube could syphon water back into the pump. From a manufacturing stand point,...
