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

very easy to use and works very well. very happy all around and will buy again.

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.

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.

Perfect for our tank.

this was bought for my aquaclear filter pump and this is the wrong size. I needed the aquaclear 70. Activated carbon is permanently encased and not refillable. .

It takes a lot to rinse the black particles off of the carbon. I ran cold water over the bag for over 15 minutes before the water ran clear. From the advertisement, I thought the carbon was in sheets, not bags. I placed the bag in the filter housing, but has seen no difference in the aquarium water. It does not keep the water clear. Will not purchase again.

The product is easy to install. I applied 3 carbons to my fish tank and the water became clear and clean after two days. It saved me a lot of time to keep changing the water. What I need to do is just to add water when it goes below the water level.

thanks

Arrived in a timely manner and as expected
