Yeah, I started with the stock
PC's in the hood on my BioCube, then wanted to add more light. So instead of just ditching the hood, and going with some
MH, I got a custom upgrade for the hood that doubled my
PC wattage.
Now I wanted to get a Clam and some
SPS corals, so I had to ditch the hood and go with a
MH unit.
I should have done that from the start and saved the $$ form the custom
PC upgrade, but live and learn.
So, the point is...
IMHO. Get the best, highest lighting you can afford now. Because, you will most probably change your mind later and wind up spending more $$.
