Fluval 404 for Bio media reactor


New member
I took possession of two fluval 404s in a used tank deal. Owner wanted everything gone. The filters are in good shape. I'm wondering if I can use one for a biomedia reactor for vertex bio pellets?

Good idea or bad idea?

It wouldn't cost much to try since you already have the filter.One good thing about the fluval is the ability to adjust flow.From what I have read,biopellets work best with just enough flow to make them tumble gently,of course it will be impossible to judge since you won't be able to view them in operation.
