Custom Aquarium lighting

I have a 144 gallon have circle reef. It's a cool tank but due to its half circle shape lighting has been difficult. So I decided to do a custom one of LEDs and t5 fluorescents. I was able to take two 48" LEDs I had and split up the boards and heat sink to fit my needs however I'm not having as easy of a time with the t5s never tried something like this and it's brought up a few questions I have never delt with and was hoping some one on here could help me. I'm looking to do all high out put two 48" two 36" and one 24". 1- dose any one recommend any places to get the parts for ho t5 in 36 and 24? Home depot only carries 48" for the high output 2 - not sure on best way to wire to do the timer controls I need. I would like to put one 48" one 36" and the 24" on one timer together and the other two on another. Will I need a ballast for each or is there w way to run them of one each? Any help or recommendations any one could give would be greatly appreciated Thanks Joe
