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

a little hard to install

Saw this reviewed on an aquarium website. For the price it was worth the try. My 20 gal aquarium has never seemed so clear! Like the 3 stage filtering.

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.

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. .

I have a 20gal freshwater tropical tank and I love these little carbon inserts, I change mine about once every two months, Ive found that you dont really need to change them more then that!

Quick ship.goid price, came in 3 pack

I must say i am extremely disatisfied with this product. I have endured the lost of about 15 fish within a period of 3 months due to this product and filter. I tried everything not believing The filter or its products had anything to do with all my fish dying. so I started checking every possible problem including cleaning my tank, throwing away food i thought might have gone bad. I tried everything. Bought countless of medicine at the local Petsmart etc. and my fish kept dying. When i zeroed in on everything i went a little pet shop by my apartment and they told me to check the filter. and i removed it completely but found nothing visibly wrong. But nonetheless i removed it completely from my tank and dug up for my old power filter that came with my tank. and since then its been like 2 months and no other fish has died. and i went back to the old food i was feeding my fish and my two remaining fish are just fine. This filter has cost me so much more what i actually paid for it and its inserts so i give it ZERO STARS. Zilch... so upset. argh... i love my fish so much.

As advertised.

Great stuff the only brand to buy

I dont regularly run carbon on my filters but I had a terrible green water outbreak due to too much fertilizers and the carbon helped clear it up in no time.
