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

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.

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.

Works well but it is a bit tedious to get it to sink

I can’t say I really noticed a difference more just decor.

Let me start with this ... I've had aquariums since I was a teenager (40+ years) In all those years I have never had a problem with my water parameters and/or cloudy water. I haven't had an aquarium for a couple of years, becuase i was caring for my elderly uncle. About 3 months ago, I decided to go back to having fish. I was constantly checking my water parameters and everything would be off and my water was so cloudy I could barely see my goldfish. I was constantly changing the water and the next day it would be the same thing. The only thing different from now than all those other years is now I'm on city water, before I was on well water. I search on the internet for a solution and I read about these Moss Balls. My first 1 was bought at PetSmart. I couldn't believe the change in my water. Cloudiness is gone and water parameters stay the same, Haven't changed my water in 2 weeks. I can see my Black Moor Goldfish, now. So I bought 2 more, here on Amazon. This is one thing that is going to be in my necessities for my aquariums. It says it is for a 10 to 20 gallon aquarium, but it works perfect in my 29 gallon.

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

My betta tank was getting cloudy and the water going stale even just a few days after cleaning it. Put in one of these moss balls and not only will my water be clear in a few days but my betta loves to play with it and push it around the tank. Great value!

I’ve seen a lot of reviews saying it looks like a teddy bears tail was cut off, but obviously this isn’t real moss. Others say it floats and I have to agree it doesn’t just sink right away, however if you hold it under water and move it around you’ll start to see bubbles and it’ll eventually sink. Patience is key! As far as replicating a moss ball it looks very nice and high quality in my Bettas 9 gallon tank and ended up sitting perfectly on the wood piece decor as shown. Lately the tanks water had been cloudy and I tried everything from water clarifiers to bio capsule water cleaners and non of those worked! I put the moss ball in the tank a few days ago and within 4 days, the water cleared up noticeably better to the point it looked like I had just cleaned it and put fresh water in. Also the smell of fish water has almost entirely gone away too unless I’m standing directly over it. The fact these can stay in for months and help keep the water clear makes this highly worth the money for anybody looking for a moss ball either for decor or for keeping the water clear.
