Aqueon Replacement Filter Cartridge 9 pack Small 6.2" x 2" x 6.2"

I have been using these filters from this seller for over 18 months and my betta boys Zen & Blue Haven have been thanking me and these filters . They are perfect and I am thankful to find here as the local big pet stores never have them in stock . Thank you for having or my betta boy would be gone .

These are good filter cartridges - well-made and easy to change - but it really doesn't matter because if you're using an Aqueon power filter, you're pretty much locked into using Aqueon replacement filters. Fortunately, they work well, and this bundle makes them available at a reasonable price.

For keeping the water clear, these work fine. I have a 2 beta divided tank. One of these filters lasts about a month & gets pretty gunky by then. The best way to keep up is to remove & replace half of the water every week or 2. I also add a pinch of aquarium salt and have a small plant on each side. In a perfect world, an under gravel filter would be great. But I could see the difference in water clarity with the half tank change plus a new filter.

These filters are getting harder to find. Only certain pet stores carry them, and recently, even the local Pet Smart stopped carrying them. I did find them at a Pet Co, but the price here on was so much better.
My fish let me know when the filters need changed! I have one that’s pretty sensitive to pollutants in the water. These are the only filters that I have found that will fit the Aqueon filtration system that’s on our tank.
I do wish there was some way to clean and reuse the filters a bit though, it seems like a lot of waste sometimes. But the filters work very well and my fish are happy. :)

These are manufacturer's replacement cartridges for the Aqueon QuietFlow LED Pro Power Filter (size 10). According to the box, the cartridges also work for QuietFlow Power Filter (size 10) and QuietFlow E Internal Power Filter (size 20). There are 12 cartridges in the box. How long they last probably depends on how heavily populated your tank is and water quality. My 10-gallon tank is lightly populated (1 beta and 6 corys) and quite clean, and based on the life of the first cartridge, I think each cartridge will do its job for about 3 weeks. The cartridges are clearly labeled "Front" to help with correct insertion and are very easy to replace.
