get two single ballasts not a dual. If on ballast inside the unit fails you need to send the entire unit off to be fixed. By having two single ballasts you can still maintain your tank with a single light. The t5's only have a 3-4" spread so they wont be able to light the stuff in the middle of your tank if the halides go down so dont rely on those alone. If you are picking up the ballast from an LFS ask them if they carry spares they loan out when equipment goes down - if they do then the dual unit should be fine for you will have a backup.

4 T5's - 3 ATi Blue Plus, 1 Purple Plus. Get the LET Lighting Retro fit kits from Reefgeek.
