It’s amazing
You get what you pay for this is amazing OK for 4 to 5 dollars to three dollars. This is a pretty good pricing that I’ve ever seen on Amazon to be honest because everything so overpriced now I’m gonna give my pros and cons about this product and honestly, there’s a lot of better pros than cons for the pros. I noticed that this is pretty good in packaging. Technically, I don’t like the blue packaging on there, but we can leave that for the cons. I separated the bio balls in the blue packaging so or the blue packet or whatever the hell you wanna call it and put it into my hang on the back filter for the quantity you get at least one for the money you wanna buy for personally I love this product this product was pretty good in my tank definitely I still need to get more bio media but not from this company cause girl no shade. This company is all right. OK another pro is this does clear out. Your ammonia is better than chemical filtration. just gotta say I use this product a lot and it’s a pretty good product for the cons again the blue packaging. gotta go change it to something like other than blue because and then the extra material on the blue packet in the code of bio balls. I’m like I gotta just cut this off like what the hell another thing is is that there’s nothing really else to give about cons because it’s not a chemical filtration product so I can’t really judge the hell out of this product so you know

Perfect
This fits in the overflow compartment of my HOB filter. I rinsed it off and let it soak in a aquarium starter solution. I'm hoping this establishes a good colony.
