I used these when I had four turtles and I thought they worked really well! It really got all the dirty and whatnot, it kept it to it - it didn't come off and float in the water.

These filters work great and keeps the tanks clean. I have a turtle so my tank gets very dirty but these filters absorb the most of the leftover food.

I exclusively use these for my aquarium. They filter very well and hold the charcoal without it leaking out. They also last approximately 6 weeks before needing changed. I will take it out on occasion and rise the outside and put it back. Works like a charm. I've tried others, however they weren't as effective. I get mine at the local pet store. I will only use these for my fish.

These biobags are inexpensive and easy to use. We dot change ours nearly as often as we should, so they last a really long time. The aquarium is nice and clean looking even when the filter is old. I buy these on a regular basis and like to have extras on hand to change out as they get gross. The filters have worked much better than the other brands I have tried in the past.

I paid $13/a box of 3 for the longest time before doing some proper research and realizing I don't even need it in my filter. I've since switched from whisper filters all together to aquaclear filters. I use filter floss in my filters now, a massive bag of it costs $3 and lasts well over a year even between 4 tanks. It collects gunk the same way as these cartridges but without carbon.

Good for the price. It helps keep the water clear. Max I'd use this for would be 20gallon tank. After that I would move up to a canister filter. This brand is good for tanks with the correct amount of fish for the tank

I have a 40gal tank for a red eared slider and she gets so yucky. But when I have in a filter with these cartridges, it makes such a difference. Last a long while, but it can be a messy clean up.
