Nano Cartridge 3pk

Don't bother wasting your money on this product. I bought it out of curiosity as I have never seen a floss filter cartridge for a nano filter before. First: it does not fit, why buy a filter cartridge that does not fit in your filter correctly. Second: carbon is useless in a tank of 5gal or less just do a water change every week. For a tank that small, it only takes about 5 min. If you want to use filter floss just buy the bulk stuff and cut your own. Realy any cartridge is just a waste of money especially this one.

Great little filters. they keep the water clear. They fit in perfect but you have to turn them at an angle.

Worked well.

These were listed as a suggested item with the filter, however they DON"T go with the nano Deep Blue filter!!

I really don't see what filtration system this fits in. I own 2 different BioMaxx that say they take the S?

They will fit if you turn it side ways. They work good for me

Returned.
