Exo Terra Moss Ball, Water Clarity and Odor Control for Aqua-Terrariums, PT2478, Green

These things are amazing. I've been using them for my turtle tanks for years, and I just bought new ones for my 2 aquatic frog tanks. I always have at least 1 in each tank at all times. Theyre cheap and easy. Just open the package and pop it in the tank. It'll float for a little until it eventually sinks. It's green and fuzzy about the size of a golf ball.

not sure how well it works yet, but she sure loves pushing it around! just for that, i’d say it’s worth it hehe

The media could not be loaded. Less foggy than yesterday, but I don't like that the material comes off. Like it shed's some. But definitely gives some life to my aquarium

Bought for my fish tank. Do not really see a difference in my tanks cleanliness.

I used to use the fluval moss balls but now I prefer these. Just like the fluval moss balls they eliminate stinky aquarium odor and clear up the tank a little. But unlike fluval's moss balls they don't shed (atleast to me they dont). And for it to sink faster you need to give it a couple of good hard squeezes in your aquarium.

I might not be very observant but I was under the impression that these were real moss balls when I purchased. Didn't even know fake ones existed and see no reason why. I have only ever used real ones and highly doubt these do anything to make a tank ecosystem better. Just some cheap gimmick for people who don't take the hobby seriously.Made in China

Loves and so does my Axolotls

Nitrites/nitrates are lower in tank with this fur ball than the other tank with the real moss plant. Looks like a cat toy at first, was skeptical, didn't clear the cloudy water because my PH was too low. This fur ball doesn't take care of PH levels..so if you have cloudy water make sure you have your PH tested. That could be the cause of cloudy water and the tank also has a blossom bloom of bacteria which requires patience, in which days was cleared by leaving the water alone to resolve on it's own. I love the fur ball. Will take days to take in water to sink itself. Snails love it to. I did come to realize this one was for turtles and there is one made just for fish. Did no harm to my fish and helped bunches. Added this same product fur ball to my other tank as well.
