Pricy for formed glass. I am not going to say it will work or not. I have thought about this for sometime but never built one. I was always concerned with reducing the lumens. They say it will not but who know if it is true or not. Alga growing would be a worry for me in the tubes but I guess you can add some bleach to the water to stop that.

Let me know how it goes.

Sorry I could not be more help then that. I still use cool tubes and air cooled hoods my self.
