Change in quality

i have bought these filter bags for a long time, and feel the last bunch i got had changed and not for the better.....

Great product

I have a whisper filter that works great. My main use for these is they fit perfect in my sump.

This 12 Pack of Large Whisper Bio-Bags

by

I have to say - That over the many years of using these filter cartridges, their value, quality and exceptional mechanical filtration have stayed the same. And that they have provided my 15 Discus tanks with the biological filtration they need, by keeping the helpful bacterial colonies healthy so my Discus stay alive for years to come.

Great Value

by

Great filter that I have used for years. It is so cheap to replace them as needed. I am going to use these until I no longer have fish!

Good value

by

Exact same bags as Top Fin, so you can substitute (Top Fin frame is slightly different, but also usable). Density has declined over the years, but still the best value out there. Also same size as one of the Biowheel, but cheaper.

I have been using these filter cartridges for more than 10 years in all 4 of my aquariums, and have not seen any change in quality (as one reviewer stated). I am able to rinse and re-use these one time to extend their use. When comparing both quality and cost, I have found these to be the best filters/filter cartridges on the market

I use these filters all the time. Easy to put together and a great price.

Changed over the years

by

I have been using tetra power filters for the last 26 years on six tanks. I used to be able to empty the charcoal, rinse them out and reuse them once or twice before replacing them. Now, for the last few years they are a once use and fall apart. It can get expensive!

excellent filter cartridges

I have 4 aquariums and use these filters in all of them. They keep the water clean and clear, catching even the tiniest bit of debris. I highly recommend both the filter cartridges and the Whisper Power Filter.
