Enhanced Bio-Wheel Replacement for Marineland Penguin Power Filter 330B Review

makes the aquarium crystal clear and balances the chemistry, although we had to change it because we chose the wrong size

The 350 filter wheels are too short, contrary to another reviewer who said they would work. I'll find a way to make it work

Not sure if this is a "genuine" Marineland product but it works. When it was new it didn't look like my original. I would buy the generic at this point as it is hard to find without repurchasing the entire unit. I don't know why Marineland doesn't sell them individually in more places, knowing that this spinner often fails on filters.

I got the wrong bio wheels; I needed 350 biowheels for my filters, I probably ordered the wrong ones which was my mistake. I received them on 06/24/14 in the evening hours. Today, 06/25/14, I wanted to use the right of return and send them back. But time ran out to return them the same day I received them! They were also damaged in transit, but still usable. This is a paper filter and can still become a 330 aquarium filter, but not perfect. I didn't take them from there from the original…
