4.0 out of 5 stars WHAT SIZE YOU NEED! HERE
By Meyer Family on February 9, 2018
I change my filters once a month, so the 12 pack lasts me a year! Unfortunately they do not really describe what size goes to what filter, so I ordered a medium for my 40 gallon filter, which did not fit. So here is the product size on the boxes that isn't included in the description!

4.0 out of 5 stars Fits TopFin, Keep Your Frame
By Mike on December 3, 2015
TopFin frame is on the left, Tetra on the right. The difference is pretty clear.

The filters fit fine and I was happy to see that some carbon packs were included. Can't beat it for the price. They do feel a little thin but we'll see how they hold up over time.

5.0 out of 5 stars $$Money saved$$
By Alexis on May 20, 2017
Amazing! The best part about these in my opinion, is the price. In stores these are normally sold in a package of 3 for about $8. So considering that you get 12 cartridges for only a few dollars more, is kind of a no brainer. I've saved so much money since switching, plus my tank stays cleaner. The box comes with super easy and clear instructions. These were the first assemble-your-self filters I've bought, but it only took me a few seconds to figure out. Always save the green bits, the little clip and the frame, as they're needed for all 12 cartridges. If you're looking for new filters, go with these. You save money, they're delivered to your door so you won't forget to buy them when needed, and they're amazing for the tank!!

5.0 out of 5 stars Fits Great on TopFin 40 Gallons Filter
By Vale on July 23, 2016
I never take the time to review items, but on this time I will because this filter save me lots of money from buying singles filter cartridge from the petstore's. I purchase the 8 pack size Large and fits great on my TopFin 40 Gallon Filter. (But please note you have to save your original Frame from your old filter or else the frame the comes in the box won't fit if your planing in using it for a aquarium like minds) Hope this review help.
