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!

I made the switch from the ceramic rings to these instead, although you can use both my filter wasn’t large enough, these also way lighter in weight than the ceramic rings.
Great find and price
