Lighting for acrylic tank

[jeepboy]

I got a 125g acrylic tank that has an acrylic hood with built in acrylic flourescent light bulb holders. It has the ability to hold 4 bulbs, the previous owner only had 2 installed. I think they are NO, but I'm not sure. Since the tank top is not euro braced, would installing 4 VHO lights in the hood cause problems with the acrylic tank top or hood?
Anyone else have a similar setup?

I have a 135 acrylic with attached acrylic hood that has two 6' VHO and 4 4' NO with no problems. I even have the ballasts for the NO mounted on the back of the canopy. You should not have any problems with what you want to do. HTH.

Not definite about the thickness, but close to 1/4 inch.
Coach, what brand take hood do you have?

I currently have a "Tenecor" soft seal 120 using 440wts of HO VHO on a Icecap 660 4 inchs of the water and i have no problems whatsoever. I did install 2 fans, one exhaust and intake on the back of my canopy to releive some heat to keep my temp 79-80.......works great. If you're not using fans it does get warm. Warmer that i would want. Over time it made not be a good thing.
