Just got done building this tank:
Two questions; what sort of reflector material will survive underwater? Will a cheap acrylic mirror really do the job? My plan is to put 6R 1B LED at the back side of the scrubber and two reds on each side, maybe angled if I can get some sort of reflector.
Second question, what cheap material (pref black) is there to put at the back of the tank, or is there a type of paint that will be OK underwater?
