### ⭐⭐⭐⭐⭐ ... my Fluval 306 canister filter and this was a perfect fit as compared to the factory piece
*by T***0 on March 22, 2016*

I was replacing parts for my Fluval 306 canister filter and this was a perfect fit as compared to the factory piece. I was able to take this strainer off that had become gunked up with algae and fit this piece right on the intake tube. Everything is working great and the price was great. There were not alterations or modifications that needed to happen, just plug it and let it go.
