Aquarium Carbon Pad – Cut‑to‑Fit Carbon Infused Filter Pad Media for Crystal Clear Fish Tanks and Ponds, 3/8"–1/2" Thick (10.5 Inch Width, 36 Inch Long)

Easy to cut, fits well, and helps keep the water clear. Good quality and works great in the filter.

This is the same stuff that comes in a Winix air filter kit, though a less expensive. You get one large sheet that you can cut to size. You can make a little template out of a piece of paper or plastic and use a razor knife to cut out whatever shape you need because it's easy to cut. I use it for the stack filter in my turtle tank and it works great. I change it out a couple times a year.

Works as described.

I was able to easily cut it into the exact shape that I needed for my Aqueon SmartClean Power Filter with EcoRenew. The filter replacements are $11 for 3 at Petco, so I am saving a lot of money with this purchase and saving time from having to go to the store. This is going to be the only way I replace these filters moving forward.

I like being able to cut these to shape! Great at reducing odor on my tank with amphibians! Also nice for my fish tank filters

Thickness and size could be better

Why didn't I know this long ago> Placed behind an inch-thick cut-to-fit piece of filter floss relieves the messy and expensive task of replacing disposable filter bags containing carbon granules with each water change.

Great filter media definitely does a great job keeps water clear., Will continue to buy.

The product quality is good!

Works Great
