Aqueon (2 Pack) Minibow Replacement Filter Cartridge Size Small (6 Cartridges Per Pack / 12 Total)

These work great for our beta fish tank. Good price too!

Our MiniBow is now a year old and these filters work. We have to replace ours roughly every 3 weeks. Its more than Id like but the tank gets dirty that fast. Tank has a single beta in it. (Issue is over feeding. Extra food makes tank icky.)

They cleaned the fish tank really well.

These are pure garbage. The filter that I got with my tank was filled completely with charcoal and I had no idea I had to change it frequently. It lasted me 4 months before I realized that but my tank looked wonderful. I bought these and they barely have any charcoal in them, they get moldy and green really quick and my tank looks horrible. Do not buy!!! Heed my warning!

These are good I need them for my 2.5 gallon tank

Works as designed

Product is exactly as ordered

This product is half the price than if you were to go to a national pets chain store. Good value!

Stock filters for a fishtank. Not much to say. These are from the original manufacturer so fitment is no issue.

Great price but I hate how often they need changed. I deducted a star because this filter sometimes washes water over it, instead of through it, before it needs changed.
