Aqualight pro upgrade??

[allincuddy]

The question?? (2 aqualight Coralife Pro 36")
Can I take the existing double ended 150W HQI and change both the 150 w ballasts to a single 2 x 400 W and run both, without having to change the fixture, that recieves the double ended bulbs?????:idea:
Thank you for helping in advance.

where do the ballasts go in the fixture? and why do you want to go 400 watt?

that's a lot of light in that little fixture, won't it melt something?

Thanks for the info and question.
The ballast is external, and I hope it doesn't melt but I will look at it again and I will add a second fan.
I want the 400 W as my tank will be hard corals, blue and Green and thought the best way to have and grow are with 400W, if I am wrong please advise as it will be appreciated. If I learn something new every day for the rest of my life, I probably would be ready to have a reef tank when I'm 206 yrs. old.
Thanks for the info and questions.

Mark, where can you buy fans from?

I went to radio shack and all they had was computer fans... Is that what you'd wanna use? How would you wire that??

Thanks

You can use the computer fans. Just check the wattage of the fans you get and space available for mounting. You could also wire a external fan with a transformer. My concern also is with the fixture. You might be better off to build one. BTW the coral life pro 150watt hqi should be equivilent in output to a normal 175watt MH giving you 350 watts. Check http://www.esuweb.com/ coral lifes website.
