BioWheel

[fishgate]

I have 2 almost new Penguin Bio-wheel 200 filters that I got as part of a trade that I am not using. Are these filters good for anything in the saltwater world? HOB refugiums perhaps?

IMO they would only be good in hospital tanks and QT's minus the carbon part

as Shifty said, Great for QT and hospital tanks.

That's what I use for my QT tank
