shawn, i had the constellation fixture delivered to my brother's business. he is coming down this weekend with it to help me build the new canopy around it. i am vaguely planning on a frame w/ swivel joints so the whole top with fixture can be moved up out of the way for tank maintenance. the actual plans have not been drawn yet, as we were waiting to get a hold of the unit. according to aquactinics there also needs to be unobstructed screens for air flow on the sides and top, for the unit to breathe.
today, i am looking into marine paints to see what it would run me to get some white inside for additional reflection, but more so to prevent new wood from warping in the humidity. I am not yet in possession of the bulbs, as i am on a budget nowadays, and dont need them until this unit is built and ready to replace my existing canopy.
some reasons i have to go with canopy with this unit:
a) my hands are in the tank way too often, and i need to top off from the top of the tank right now, so the unit needs to be out of the way.
b) t-5 are super bright and i dont want the light escaping the top of the tank.
c) my tank is a custom acrylic and has 3" euro brace type lip around the top. this design does not lend itself towards canopy-less system, as it is aesthetically unpleasing.
