I have been all over the internet, and cant find any retrofits for an eclipse 12 gallon. I have completely removed the old lighting fixture because I want to start a mini reef. This will be my first reef tank although I have about a years experience in saltwater. A place named customaquatics.com or something like that used to have a retrofit, but they closed down. Please help!!! I am looking for a power compact addition. The longest point of the tank is about 18 inches long, but has a bar down the middle which supports the internal filter that needs to stay in the tank. As always, price is an issue, I am but a poor college student.
