Wheel works great. No issues except one wheel when delivered was broken. A manufacturer problem. Called Chewy and they sent another one out. Thanks.
Just What I needed
on Jan 30, 2021
Chewy was the only place I could find the biowheel. I have been having terrible issues with algae and cloudy. I had to completely change and sanitize everything and so do a new set up. The biowheel was the last thing I needed. The tank is looking good and I will be back as a customer. for other aquarium supplies.

This does not fit a 200 series filter, it's actually for a 150 series, 200 series do not have those clips on the end, they are perfectly circular

Bio Wheel purchase
on Feb 5, 2020
Purchased two bio wheels for an old Penguin 330 which was missing them. The wheels were about 3/4 inch too wide for this filter. Rather than send them back, I shortened them to fit, not as difficult as you may think, and they now are the correct length. My only problem with this is they are a little larger in diameter and kind of rub. By resting on the top of the wheel bracket (?), they now rotate properly. Otherwise excellent product. Thanks.
