Re: [APD] PLL Lights

Hi! Scot,

I do have a pressurised CO2 system & I also does macros & micros. Do you
think even under these circumstances, I might have algae problem due to
excess light. In fact I was thinking of adding one more 36 watts PLL light
so that the watts/gallon figure will reach 5+. I guess even EI advices that
kind of high light.
