    Add to cat litter

    By Bunnie on Oct 28, 2021

    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.

    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!!!

    By on

    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!!!!

    Didn't work in all my tanks

    By on

    I have 3 tanks I wanted to put this in to try out. It worked in my largest tank. However my other 2 tanks I had to do a water quick because it turned the water a different color and my fish didn't look happy , after the water change they looked ok except in my one tank I lost one albino baby pleco and 1 pearl gourami
