SunSun HW-304B First Impressions

They do the job well!

It made no sense why one was ten and the other was twenty. It was a struggle to keep the water clear before i got the goldfish. It eventually begins to decompose into ammonia which is harmful to your fish. Right now I am letting the filter work it's magic. The Tetra Medium bio-bag slip easily on an original Top Fin plastic holder. Also work great as filler for canisters and other filters.

SunSun HW-304B Final Thoughts

I would buy it again.

I have a Top Fin 10 power filter and these cartridges fit perfectly. It was nicely packaged and is a high quality filter material. Also work great as filler for canisters and other filters. Just be super careful with the tubes! Don't shut it off for more than a few minutes at a time. I use two layers of floss before the water goes to and through my chemical media. The injection molding for the plastics leave a lot to be desired.
