Grim,
I may be considering placing it directly on tank. Not entirely sure yet. Hopefully it doesn't make the water too hot since I do not have air conditioning.
Anyway, I do not understand what PAR is exactly, but following your directions how do I set up my timers. The info on the constellation says --- Three switches on fixture for dusk / dawn lighting or for reduced lighting applications. One switch for 3 rows, another for 2 rows, and the last switch for 2 rows. Also, separate power cords for each of the switches.
Right now on my tank I run my actinics one hour before, during, and one hour after white light. Will this be similar or is this a whole new way of lighting?
Thanks
