Top Fin EF-S Element Filter Cartridge Value Pack 12 Month Supply 2.1 in X 3.7 in

Used in my 3 gallon tank.

Great Value.

Super Easy to replace

Have yours these filters for over 2 years and Amazon ordering made it easier

Ugh, so hard to track these filters down for whatever reason. It really bothers me they charge so much but it is the best filter for my fish tank. When it arrived the box of filters inside of the package was pretty beat up (bent, loose packaging) and some of the filters had bent tabs at the top but they still work. ALSO, this is not a year supply, many tanks use two of these filters at a time and they should be rotated every month or so.

Not as good as a replacement I bought before

I just got my betta fish and the filter I got was the Top Fin filter and they said I may need to get a different filter next month because these were on back order and she didn’t know if she could even get them for me. One little search on here and I found them! And definitely Big Bang for your buck!

Easy to replace and easy to use

Sheerness, thickness, great quality and value and money priced equally!

Perfect fit for the aquarium
