These are really really small. Won't work in my pond filter Don't have the right filter for them. Did not realize how small they were Would like to return them if possible
These bio-balls are very small, like only 1/2" in diameter. The photos and video associated with this product show a much larger ball, the size of a golf ball.
To be honest, these don’t do a thing your better off with ceramic rings from sea chem
Got here in time to be properly seeded with bacteria while I treat my tank with antibiotics. Glad the bio filter arrived in less than 48 hours, just wish each box actually had all 90 promised Bio-Filter Balls. Otherwise, perfect as always Chewy! (Pretty sure the packaging of the filter balls is not a Chewy error, but rather a reflection on Marineland. 4 star rating is *only* due to Marineland shorting the 3 packages. Chewy is amazing!
