Which one?

[Icefire]

Well with a budget, I'm looking to start a reef in a 50G 36"Lx16"Wx20"H. Just like 6-7 small fish in the run with easy soft and *maybe* some hard coral.

What to choose? with 36"x16" canopy:

T5 2x39w HO 36"

tube 46$ for 2
Ballast 39$
Total: 78W 85$

PC 2 tube 65W 24"

tube 25$ for 2
balast 29$
Total: 130W 54$

PC 1 tube 96W 36"

tube 21$
balast 29$
Total: 96W 50$

In the run, I'll probably double it which would be best?

Also, 6700K, 10000K & 50/50 to go with Actinic ??
