If your MH retro don't have a glass shield, be very careful about splashing.

If your MH retro doesn't have a glass shield, you'll be irradiating everything in the tank with dangerous levels of UV radiation. DE bulbs do not have the same UV shielding built into them as SE bulbs.

manderx,

I'm in Lynchburg, anytime you are over my way let me know. You are more than welcome to stop by...

ade,

Thanks, all of the corals seem to be doing well. The sun polyp seems to be getting happier, it actually opened up a little last night and ate some mysis.

Virginia Reef and J. Montgomery,

Thanks for the heads up, the retros came with nice heavy glass shields. So even though I am running the tank open top, there is still glass on the MH pendants.

Looks like you're good on the lights. Your height over the surface will only affect temperature. If that's good, you're good.
