Should I go with a 150W MH or a 250W?

[civileng68]

I have a 29 gallon tank with 135W PC lighting right now.
I am keeping the current lighting and adding a Metal Halide Pendant behind the PC lighting fixture (it will fit if I move the PC lights forward).
With already having 135W PC lighting should I get the 150 W MH or the 250W MH?
My goal:
My goal is go be able to grow hard corals along with soft corals. The only fish I want and have are 2 false percs. I mainly want a tank with beautiful corals and inverts.

Are you talking about Double ended MH or single ended. SE come in 175w, 250w, 400w, DE come in 150w, 250w, 400w.
I think if you put a 250w MH on that tank you will have some heat issues.
If you want MH and want to keep sps then I would recommend the 150w Double ended, you could keep anything you want. Heat may still be an issue, but probably not as bad as a 250wk

The actual light I want is: PFO Lighting HQI Mini Metal Halide Pendant
It's a double ended bulb. Im simply going to move my 135 PC light forward and then somehow rig it to where I get the MH light behind it over top of the water.
I'll go with the 150 I guess.

for a 29 gallon the 150w would be perfect, a 150w DE metal halide is very compariable to a 250w SE metal halide as far as light penetration and I believe the Par is very close also.
You can keep anything you want in that tank with that lighting.
