Fluval C3 Zeo-Carb, Replacement Aquarium Filter Media, 3 Count (Pack of 1), 14018, white

Not too expensive

The media could not be loaded. This by far is the best for making freshwater clear. I change it once a month. Good value. Great performance!

Clear beautiful tank

Although this filter (c3) has many parts to buy and change these units are very nice. Granted they are just little pieces of foam, but at 5 dollars it was great finding them here, and not paying 12 bucks. You can get them other places online, but they are more expensive. As for stores like PetSmart, no they don't carry the C3, C4, any of the Fluval products. Very irritating. I suggest you order them way before you need them, because you won't find them without waiting for shipping. Order at least 2 at the 5 dollar price, because the c3 filter uses these very quickly, and they are hard to clean out, or reuse.EDIT*These foam pieces rinse out a few times with little fish debris in them, but after a while they start breaking apart, and becoming flimsy. Esp if you use hot water to rinse them.Save some money and buy Marineland Rite Size Filter pads. They last forever, and can be cut to fit perfect in any of the C3, C4 etc models. They collect just as much debris at a fraction of the cost and rinse better and last longer. OR you could buy these over and over and keep throwing five dollars plus shipping away.

El material filtrante de los filtros fluval es sencilla y eficiente, no hay comparación con otras marcas, llego en perfecto estado y funciona de la mejor manera

Not much to say . Fluval products are always good in my opinion.

Works well in Beta tank

Because of the nice 'add-on' pricing, I decided to try out these instead my usual buy of loose carbon that I then stuff media bags myself for the (InTank) media rack in my BioCube. I had read on some website that AquaClear/Fluval activated carbon was some of the best on the market, and so far, I have to say I agree with those claims. My water is clearer than it has ever been with the loose carbons I've bought. Obviously this pre-packed stuff is more convenient than stuffing your own bags, and the price flat out can't be beat so long as this remains an add-on item.If you have a smaller system that you can fit one of these packs into I'd highly recommend this brand of carbon. Seeing how completely crystal clear the water in my tank is now (I didn't realize how NOT crystal clear it was until using this carbon) I will continue to use this brand exclusively. **Note: carbon only makes your water clear and takes away the fishy smell of the tank; it's a polisher, not a cleaner. Only water changes will clean a tank.

Very good product. Fit well into my filter and does the trick. Last a long time and can be washed and reactivated in the sun.
