AquaClear 20 Activated Carbon Inserts, Aquarium Filter Replacement Media, 3-Pack, A1380

Its super cheap and works great. I usually just recycle these but at these prices I say just buy them.

Nice cartridges that drop right into a hang-on-back aquarium filter. I put it in my filter after treating my tank and the discolored water cleared up within hours.

My pet store where I normally buy closed. Not everyone carries this item. So, finding it online was great. I didnt need a 3-pack since I change the carbon filter only once per year.

Perfect

you can not go wrong with Aquaclear products, have been using them now going on 8 years and have always been 100% satisfied!

Item worked as expected. Fast and efficient service.

Have purchased many of this item before. What can you say, they work. Will be buying more in the future.

Works fine.

I had to replace an older filter that stopped working, the activated carbon put in the new pump/filter helps keep my fish tank stay cleaner longer now.
