making a small nano and have a quick question regarding lights.
am looking at putting in a small power compact light, ie new energy saver type bulb 6400k 10w.
there will be approx 100mm clearance between the top of the tank and the raised cover so there will be plenty of air flow.
the raised cover will be 200 x 200mm and a depth of 100mm.
with this much air circulation is there any need for ventilation holes?
do PCs create enough heat to change the water temp?
if so by how much?
your thoughts and comments are appreciated.
