Sounds exciting Jim, I thought for sure you would be going a different direction than the VorTech after your issues with the 20!

I think you'll love those LED to. I was very impressed with the ones I got off of eBay!

LED are for sure the way to go, particularly if you like to see your corals in HD!! I just mounted to PB LED's to the DT and it truly is amazing how the water shimmers and dances!

What all are you going to be keeping in this cube anyway?
