Hi, I am not completely happy with the filtration of my Penguin 150. Its on a 30 gal tank. I am considering buying a small Fluval to add to it. I am unfamiliar with the Fluvals. What kind of current do they produce, and is it adjustable? Also, has anyone found a good way to modify the current coming out from a penguin? Just to diffuse it, or spread it over a wider area to make it less powerful in one area of the tank? Thanks for any thoughts on this.
