I use these for my Tetra Fauna Viquarium and they work great. They pick up any and all sludge from my lizards water feature. I love that they are versatile and can be used with so many different animal habitats.

This bag is really good and I use this to pick up my dog poops when we go out. I know it's big but I have a huge dog and he poops a lot when we go to the bathroom so I need a big bag. It's will totally buy this !

I actually use these in a non tetra filter unit because I know the bio bags work so well.
My 10g tank stays clean for weeks with 2 nasty gold fish.
Anyone that has goldfish know that they are messy!

High quality and minimum dust off the filters. I've never had an issue with them. You can find them at any pet or aquatics store. Theyre not a bad price either.

Work well, lasts about 2 weeks and then starts to cloud up the water. Will repurchase as I can get them at my local grocery store

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.

Bio bags always worked good for my 55 gallon aquarium and I never had any problems. They help keep the water clean and clear.
