More info and photos.
The lid is lifted to access the tank.
The back is open other then the support that rest on the top rim of the tank. So if I wanted to use HOB filter's I will have no issues.
I have had no problems with condensation, but the fish will splash water on the underside of the lid.
I am in the process of making glass lids for the top of the tank, similar to what can be purchased in stores.
For the lid I made a frame then covered it with oak plywood. I sealed the interior surfaces of the canopy with a wood sealer then painted with paint. The lid is approximately 1 1/4" thick.
And for the lights all are T12 40W bulbs. I started out with three 6500k Daylight and one Coralife Actinic Blue. In the above photo one of the 6500's was remove and I put in a bulb that will be replaced with another Coralife Actinic Blue.
