Great filter media and you can cut it into whatever shape or size you need

You will be able to cut cost of proprietary filters by cutting you own. These are very washable and reusable even under heavy loads like large goldfish or koi species. 8 tanks to take care of and a roll still will last me 2 months or more. A great value for the money and who does not want to cut costs these days.

It takes a lot of time cutting it to shape and size of filter and in the end it doesnt make a difference, Ive been in this hobby for 10 years and I bought this once and I will never buy it again

I have been working on cycling my aquarium for about a month and a 1/2 now and have really been struggling with the nitrites. Despite the many water changes and beneficial bacteria Ive been adding in they just havent gone down and have been at a dangerous level. My nitrites were reduced overnight just by adding these to my filter cartridge. I dont think they were even advertised as nitrite reducers but they certainly have done the trick when nothing else has. This is such an affordable replacement for the carbon filters I have been using and they offer sicker and way more protection and can be customized according to size and preference. You can even add 2 layers of these for even more filtration. No more pricey rip off cartridge filters for me!

cleans 44 gallon aquarium very well

I cut out sizes for my caddy in my Nuvo 60 gal. Got around 8 or 10 out of one sheet. Absorbs very well catching the bigger particles on the more open rougher side than straining through the finer side of the pad. What is nice is that you can easily wash the pad and reuse. Washes out easily under a kitchen faucet. I try to change out pads daily. I am set for a long time with this purchase.

This medium really keeps my aquarium crystal clear I love that I can cut it to fit any filter.

Works perfect.

Fits my sump perfectly

Ive got a pair of aquaclear 30 filters for my 29gal tank, and for the longest time the water was always slightly cloudy. Replaced the sponge that came with the filters with two layers of this and one layer of the water polishing filter and its already noticeably clearer the next morning, and the nasty raft of protein slime bubbles was half the size it was the night before. Absolutely loving having a cleaner tank. (please ignore the diatom/brown algae on the plant leaves and glass, thats definitely on me, Mistakes Were Made, crashed the tank cycle in a failed attempt to fix something else and now im fixing it all)
