Hi GreenGanja!
I am guessing that you're talking about the large Eclipse 3 system, probably 27 to 37 gallons? (As opposed to the Eclipse 3 gallon tank?)
I've read about people retrofitting their larger Eclipses and if you look around online you will see that some people have figured out how to do this as a do-it-yourself project. Others have used retrofit kits made especially for Eclipses. I couldn't find any companies that were still manufacturing Eclipse retrofits, though.
However, J&L Aquatics, which is local, carries retrofit kits. I don't know which size would work best for your Eclipse, but they have quite a few kits by different manufacturers.
