Lighting watts per gallon

[Cujo#31]

I’m sure it’s been said already, too lazy to read all replies. Watts per gallon can be misleading. PAR is the magic answer. Beg, borrow, or steal a PAR meter and keep your corals where they get ideal PAR numbers. If you decide to go with Radions be VEY CAREFUL. Radions are very powerful and you can cook your corals if you do not acclimate them properly to the light intensity.
