lighting upgrade
I have recently changed my lighting from a single 175W 5500k phillips blub to a dual 175w 10000k Ushio lighting system. I am continuing to use two t3 attinic NO tubes to complete the daylight cycle. I've upgrade the light hood to accomodate 4" fans and raised the hight of the bulbs to 10-12 inches above the water. Heat is not a problem.
My question is should I use an acrilic cover over the top of the tank or leave it open? Is there a benifit? I'm also looking for an affordable set of light reflectors. Does anybody have any suggestions where to find the best deal?
Thanks for any help
