Wanted to clarify to other readers... This filter is not a carbon filter and does not claim to be, granted there is a small amount of carbon inside the filter but this is a clearmax filter and not a poly/carbon filter. I use one of these on one side of my U2 power filter and a poly/carbon filter on the other side and it works just great, water is crystal clear all the time and no algae.
I got these thinking they were the same, or at least as good, as the other poly cartridge for my fluval and they're not. There's hardly any carbon compared to the others ones having one side be carbon, and wear out very quickly.
Great price....not carbon filter
I thought these were the correct “carbon” filters for this Fluval filter but there’s not even a tablespoon of carbon in the ones I bought. I’m going to buy a box from nearest pet store and compare but I’m pretty sure these ones are defective - all 5 boxes
