I used to have Eclipse systems with the Bio-Wheel in 1997 and 1998 or so. They worked great. I wandered into a pet store for the first time in ages the other day and I ran into a Penguin 350 filter, which seems to include the same Bio-Wheel as the Eclipses. This may be a bit of a stupid question, but what do I need to get besides the filter? Will it fit into any size and shape of tank I buy? Then what do I need besides the tank itself... lighting? Heater? It was all included in the Eclipse system, and probably still is... would it be too hard for a beginner to set it all up separately?
