Switching Lights . . . Best way to do it?

[jorjef]

I started with 2x48" T5's on a tank that is if I remember right 20-22" deep (77 gallon) and went to 2x AI Super blue's 8" off the water at 50-65 percent 50 being white and 65 the blue... My tank is 99 percent LPS and no problems. I haven't increased intensity a whole lot since then (close to a year now) I did once and things weren't happy. They might have adjusted and been fine but i went with the ' if its not broke don't fix it' and set back to around the original setting... Too much at stake and too chicken...

I think two lights with your tank depth at 100 percent would nuke your LPS
