Exo TerraExo 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.

Pros: It's about the size of a baby turtle (good or bad thing). Well trimmed enough and the moss doesn't fall off. Dark green color. Looks like a soggy trained green cat hairball. It can potentially make your aquarium clearer and reduce odor indeed. Can also be a fun decor to add and for your pet to interact. Lastly, it's very cheap.Cons: It's synthetic material -- it's not real. It also has to be replaced, about 2 months or if it isn't functioning. Can get ruined and eaten by bigger reptiles.Overall I like to keep it as it's a nice decor for my Ouchita turtle to mess around.‼️Important note: If you want to keep this submerged, you have to squeeze very hard until you hear a crack sound, or place it at a sink and crush it with your palm, and boom you can submerge it!

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.

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 love the look of it, but it won’t sink.

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.

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!

Does just as it claims. My tank is pretty clear in color after introducing the moss and it's a nice addition to the tank decor. The ball is about the size of a golf ball. Two for one, for a 30-60 gallon tank, is a great value when it comes to the price for 2.
