Tetra Whisper ATS26170 Assembled BioBag Filter Cartridges, Large 6 Count

Love these bio bags....a main staple for any aquarium...other type media can be put in bag for there is enough room for addition. Just the best!

Works great

Came all stirred up, carbon everywhere but all good!!

Will keep the aquarium clear and the fish happy. . .and alive.

It was not the same replacement filter that I needed. But I had opened one box so I can use the charcoal filter bags and charcoal with my assembly and that will work.

Perfect!

Very good product, very pleased, fast shipping, looking forward to more products for them

On time and always correct!

I like the fact that these are assembled and ready to use,perfect!

Great product and price as well.
