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

Larger than the stock bag, but Im not about to complain about that

Works well

I am really happy with it! Keeps my tank clean. Works great.

Good value for the money but I ordered the wrong size.

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.

Convenient, thanks!

Works as expected and will purchase again if needed.

I like these. They fit well and do the job. But I think the price is a bit too high. I buy bulk carbon instead with a cheap media bag.

I have used these inserts before and have had excellent luck with them. I am glad I can purchase them in a three pack. I wish they came in a six or twelve pack.

Great
