Hi, thanks for looking, im planning on building a wood hood for my 48inch 55 gallon (200L). Its gonna be a shop light in the hood without glass top on tank. I was thinking of enclosing the wood top except some cut out in the back for filter. Is this a big problem. Will the light become too wet from condensation? Will the wood get too wet, im gonna stain or paint inside white to reflect more light.

Questions on tank balance. Im doing low tech setup. See it

Am i using too much light with 2 40watt fluorescent tubes. I dose 1/2 flora pride. No CO2. I might reduce light to 10 hours with more lighting. Will I grow algea. I do water changes weekly.

Any other advice. Do I really need a glass top to protect shop light?
Can I still get by without CO2?

I have had a very different experience than Trallen44.

I have had shop lights just resting on top of my 90 for years with no issues. There has been some condensation and a little rust after 4 years. But I do not have a canopy, I would expect that a canopy will keep more moisture in the lights. If you prime the wood well, I have heard oil base primers recommended and put on several coats you should not have a problem with the wood.

My lights are over driven x4 and I ran it without ferts or co2 for over 2 years. I have a heavily enriched substrate however. I run them on a timer and have no issues with them coming on. In fact, my cat knocked the light into the tank about 3 weeks ago, they still work just fine.

If you click on the 90 gallon in my signature you can see how I set up the substrate.

Best of luck with the tank.
