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.

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.

product is fine but is not clearly labelled as not being a real moss ball, but merely a replica !! still sinks in the tank and looks fine, but if you are wanting live plants in your aquarium this is not that.

Why did you pick this product vs others?:These little moss balls are awesome for my aquarium! I have a sorority of female bettas and these moss balls help oxygenate my tank and improve the quality of water. Highly recommend!

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

I mean I maybe dumb but I was under the impression that this was real.. nowhere does it say that it isn’t and with all the benefits it claims to have I just assumed (my bad) also didn’t really help anything at all and collected all of the stuff at the bottom of the aquarium so now it’s an ugly ball lol.

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.

Great product
