excellent product
Excellent price on an excellent product. Filters work as advertised. Much less expensive than buying from a pet store.

Spend the money. You won’t regret it.
These are FAR superior at filtering and keeping your aquarium healthy than generic off-brand filters. I tried saving money and regretted it. My fish are now heathier, the water clearer and tests healthier, and they last longer (sometimes I had to change the others every 2-3 days). Very much worth the money!

Effective and Convenient Aquarium Filter Cartridges
The Aqueon Aquarium Fish Tank Replacement Filter Cartridges are perfect for keeping my tank clean and healthy. This 3-pack of extra small cartridges fits my filter perfectly and does an excellent job at removing debris and maintaining clear water. Installation is quick and easy, and the cartridges are durable enough to last through multiple filter cycles. I also like having a 3-pack on hand so I can replace them as needed without running out. Overall, these are reliable, high-quality filter cartridges that help keep my fish happy and my tank looking great.

They work well and are inexpensive for their intended purpose.
They keep the circulated flow from having nasty algae visibly floating around the tank’s water. Let’s be honest here, if you are worried about a critique on a small filter, for a small tank, for small inexpensive fish, you may be worrying about things that don’t matter.

Fish tank filter cartridges
These are just as good as what you buy in the pet store. But at a much better price.

I'm burning through a new filter every few weeks but the fact that they keep up with everything I do makes them worth every penny. I've changed fish loads, substrates, plant configs, everything that can possibly be done. The fact that the filters catch all the junk I put in there and keep the tank running (a 30 gallon tall) is a good thing. I do have to order these a dozen at a time now however they are still cheaper than buying locally - so just plan ahead as any fishkeeper should. I'll be adding another aqueon filter product just because of the good luck and ease of use so far.

This filter really did a great job of removing excess gunk from our betta fish tank. Definitely helped keep the nitrate and nitrite levels in check! must replace semi monthly - monthly (in my experience).
