Advice on when to get new lights?


New member
I'm using 12k Reeflux on ARO electronics and they are 8 1/2 months old at this point. I've been having some issues in my tank with keeping my Mg up and recently revised my whole sump/fuge area, so my corals not looking great could be attributable to several things and I can't use them as a real barometer of what kind of shape my lights are in. I have taken steps to correct most of my problems, but this is my first set ever of MH lights and not sure exactly when I should be looking to change these guys out. Anybody with experience with these lights in particular or just general opinions on when to change out? thanks
