I have been considering upgrading from a T5 to a MH lighting system but here's where the Question comes in? Is it okay to use a metal halide 400 watt compaq bulb. Will that work? or does it have to be one you buy from someone selling them with high prices and a fish tag on them? Also will I have to put a chiller on my tank if I purchase a light set like this? I have a 72 gallon bow front tank. How many watts should i have on my tank or number of metal halides fixtures? _________ Sincerely Tom Last edited by 72RunningBlue; 05-12-2008 at 01:26 PM.
