thanks for your help said:
Yes they will crack the glass top. I cracked mine, but was able to save the fixture before it fell in the water. I would take the Sunpod off the top immediately.
You could make custome supports over the tank using 1/2" glass, wood, or metal. I had custom glass supports made by addison glass and secured them with super glue.
I eventually did the DIY light hanger kit(see last months reefkeeping article on RC). This setup allows me to raise and lower the light fixture. I think you will be happier with the stilts so you can hang your T5's as well.
I would suggest you go the metal route and cut notches to secure them on the rim of your tank. You could have this fabricated and painted by yourself within a an hour.
You will have better control over the temp, more evaportion and fish losses with the open top."]
How long did it tank for your glass top to crack?
