Aquarium Masters Replacement Aquarium Carbon Filter Cartridge for Whisper Power Filter 10, E, J, MicroFilter & 10i, & The Old Top Fin Power Filter 10 and Old 15 Model 10 & 30!

Does NOT fit TopFin 10. This filter is too wide. The original TopFin filter tapers significantly at the bottom this one does not and will only go in half way.

These DO NOT fit the Top Fin Power Filter 10. I bought these as a replacement to the filters that I can no longer get at my local pet store. The product clearly says, both in the item description as well as on the box, that it specifically fits the Power Fin Power Filter 10. It does not. After struggling for 15 minutes with this filter I can plainly see that it fits in the first half of the guides on the filter, but stops halfway down and does not fit.

So i have this stupid Top Fin Silentstream 75 Power Filter with cartridge. And Anyways I'd been using the cartridge it came with for about a month and a half now and kept searching and searching to find a filter cartridge similar to the ones i got with the filter. I found this, bought it and it was so tiny. Duh! But i got 3 so i put 2 in one slot and one in the other. Stupid filter, stupid un-buyable cartridges! If anyone finds them please comment below this review!. I got the starter kit for $100 on a sale, only problem has been i cant find replacement cartridges, I was about to buy a whole new 75 gallon tank filter with available buyable cartridges. I gave this review 5 stars because well atleast i have some sort of activated carbon lmao.

These filters are not the best. They could use more carbon in them and, for some odd reason, they get filthy way too fast. Amazon does no carry many choices in the 10 gallon aquarium filter department, so I am stuck with these. Hopefully, either the manufacturer will make these better, or Amazon will carry more variety of these types of filters.

This filter did NOT fit my old top fin power filter 10 (as the product description said it does). This filter was at least 1" narrower and a couple of inches shorter than my filter opening slot. I had to return.

These replacement filters are much better than the ones that came with the original filter and at a much cheaper price!

I have been using another brand sold by the retail pet store for some time. OnNe thing I noticed within about an hour is how much clearer the water appears to be vs the other brand. Would highly recommend.

Finally, a medium size filter replacement that works and fits my Tetra water filter.
