Here is the hood stained and painted. I used white paint on the inside because it reflects light. That paint is really primer, but it is totally water proof and holds up to aquarium use really well.
Now the fun part. First I needed to vent the hood - if I don't the heat builds up in there really bad, overheats the tank, then when the lights shut off you get condensation on everything and short out your electronics
So! Fans and vent holes it is. These are the vents, you can see I got a little creative with my new tool.
Here you can see my 18 W Lamp,.. this is the one that will run in the morning - this is a simple under desk lamp that you can get at home depot for a couple bucks. I put a 5500K bulb from Petco in it, and that cost more than the whole fixture lol. The stock bulb is shown in this photo though.
More on ventilation,.. there will be 2 fans, controlled by a temp controller on my Aquacontroller,.. If you don't have one of those, running them the whole time the lights are on works wonders - that's how I used to have all my planted tanks.
I will have one more fan BTW,.. I just haven't bought it yet - these are simple 12V computer fans that are $2 at frys electronics.
You'll note that I left plenty of space on these - In the past I've had to add more, or make them larger to deal with the heavy lighting on Reef Tanks,.. so I always give myself plenty of leway.
