plastic center brace and MH

[martym]

I am putting a 50g reef system together. The tank has the plastic center brace. Th3 250w MH bulb sits right above it. The problem is, I had the light running for 5 minutes and this brace is hotter than I want to touch. Will the MH melt this brace? The lighting system is a coralife single 250w mh with blue actinic CF. Fixture is on the legs that come with it.
I wish I could just remove the plastic brace.

Thanks for your help.
