o.k. i'm purchasing (2) 2x13watt pc kits, now the reflector is 15 dead presidents each, should i just use a mirror, i could cut pieces of mirror and cover the whole inside of my canopy for the 10 gallon.
unless the edges and back are sealed a mirror will "tarnish" rather quickly around that much moisture. Buy the reflectors as they curve around the bulb somewhat and reflect more light into the tank than a flat mirror would.
