I exceed the 4 wpg rule...

300 watts MH over 66 gallon

I've heard of people going up to 7 or 8 wpg. But not without CO2
injection!

And I definitely would not recommend a newbie try it. Those super-bright
tanks
are for experts only.

yes I agree...

without CO2 injection at those light levels is a BIG invitation to algaes...
even if it was only 3 wpg...
