Re: Bio Media for HOT 250?
Concerning media for Magnums. If for some reason you want to use bio media for the magnum then I would suggest something like the bio media used in the Fluvals or the bio media used in the BioLife filters such as the BioLife 55. I have not kept up with the changes in bio media but these “ceramic” media are a lot smaller then the Bio balls I had in my trickle filter. You would want as many pieces of bio media as possible. The more the better, so the smaller the better? Jimmy
