Top Fin Retreat Filter cartridges RF-S (3 Count)

They work sooo well in my tank and I don’t have to change them out very often

Works great in my little fish tank and betta has been alive for 3yrs and don’t have to clean as often

My fish tank really needed new filter an this on is good it really is a good filter

The filters I needed at a good price.

These filters came in looking normal! I use them for my beta fish tank and they always do the job but when they came in there was black dust in the box or on the filter I couldn’t tell where it came from. I don’t know if the black residue is supposed to be there, but i washed it under cold water and it seems to be working fine so far!

great price

Needed for tank that was gifted to me. One filter only last a week or two. Even with rinsing they dont go far.

Bought this for my Beta fish
