I'll be building a hood for my 20 gal
in the next few weeks.
dimensions of tank are 23.6 inches long and 11.8 inches wide. I'm thinking of putting 3 15W NO fluorescent tubes in there. My plan is to build a seperate compartiment in the hood for the ballasts. I think I'll need to buy 2 ballasts, 1 for 2 tubes and 1 for 1, correct? They will sit on top of the actual lights, seperated by 0.4 inch thick wood.
Do you think I'll need to build in fans in the hood to cool down the ballasts?? And the 3x15w NO fluorescent tubes, will they also need cooling down?
I've already drawn out a hood design, I'll try to get that online in a few days.
For fans I would install a computer power supply in the same compartiment as the ballasts, installing a fan on each side of that compartiment. This compartiment will be accesible through a lid I can open with a set of hinges. measurements of compartiment: 23.6inch x 7.8inch x 3.15 inch.
So anyone have an idea what cooling I'll be needing?
