How do you use this for fishes? I have a 65 gallon tank.
Answer by Chewy • Oct 23, 2017
Use 8 tablespoons per 10 gallons of aquarium water. Place in media bag or media basket and rinse thoroughly in cold water to eliminate dust particles. Replace every 2 - 3 weeks (sooner if foul smells or water discoloration occur).
Is this a good product to use in a goldfish tank to help keep the ammonia low? Do I still use carbon in my filter systerm?
Answer by Chewy • Apr 07, 2018
Dual-action chemical filter media keeps pond water clean, clear and fish-safe. Marineland Diamond Blend Carbon-Ammonia Neutralizing Blend combines fast-acting Black Diamond Premium Activated Carbon and super-effective White Diamond Blend Zeolite for superior pond water quality. It effectively removes dissolved organic waste and odors as well as toxic ammonia and chloramines. For best results, fine media must be placed in a mesh bag inside of the refillable media container to avoid leakage into your aquarium system.
How much would you recommend for a Betta tank of 5 gallons?
Answer by Chewy • Aug 10, 2021
The manufacturer recommends 4 tablespoons for a 5-gallon aquarium.
I see I have to add 8tablespoons for every 10 gallons, My question is if I have a canister filter and my filter carries 3 carbon pouches do I need to add one pouch of this product and the other ones just fill with regular carbon or do I just fill the other two pouches with this product?
Answer by Chewy • Jul 02, 2020
This will depend on your individual tank or filtration needs. If you have goldfish, it is recommended using this in place of just carbon for all three pouches since goldfish produce a lot of ammonia. The same is recommended if you have a brand new tank or a tank having an ammonia issue. For day to day average filtration, one pouch of the blend with two of carbon is suitable.

Crystal clear

I only have two fish and a 20 gallon tank. However, they’re goldfish that continue to grow to be 7 inches so they put off a lot of ammonia and other kinds of water contaminants. If you were to look at my order status on Chewie you would find that I have tried 7 filter systems. I finally found a system that works for my tank. I use Whispers empty filters, and filled them with Carbon Filter Medium. I hot glue the filters closed and use them as I would other filters. I did do research On using the hot glue and found it is OK for aquariums. But if I were you, I would do research myself to find out what is safe for your aquarium. The water is amazing, I still change water every two weeks, half tank, but I think that’s because of “my paranoia“ of my fish not being able to breathe. I would recommend Carbon filter medium to anyone who is having trouble with the cleanliness of their water in their tanks. I would also recommend the Whisper empty filters to put that medium in.

I use in catbox

I have used this in aquarium filter. It works real well to filter the water. I also use this in the catbox. Every time I scoop the cat box I put about 1/2 cup to 1 cup ,sprinkle over the top of the cat litter. It definitely helps absorb the smell of cat pee and poo.

Add to cat litter

O M G . . . works amazing for my CAT LITTER. Bought to mix in with the clumping cat litter to help with odor. Safe for the cats and better then purchasing yucky chemicals or fragrances.

Help on smell dog yard

So I used everything under the sun to eliminate dog order smell in my yard. I sprinkled this down and within a hour the smell was gone. Thumbs up

Good product for a reasonable price.

I usually use Ammo-carb, but it has been unavailable for quite some time, so I decided to try this. It seems to have a bit less charcoal than the Ammo-carb, so I added some extra till the blend looked similar to what I've been using. It seems to work as well and for a lower price.

Sqeaky Clean Water

Love this item. I use it to filter a turtle tank and the tank has no smell. We all know turtles can produce a lot of waste.

Everything I needed!!!

My goldfish are very messy. I needed something to take out the ammonia. The water would start to take on a yellowish color. I used this product and have used it this way everytime. I cut the bottom of a stocking (pantyhose) and use the toe end as a place to hold the carbon. Put enough in there that looks like would be in a filter and tie up the end. Rinse with cold water till the carbon runs clear, and stick in your filter!!!! With this product its flawless!! Thank you Marineland!!!!
