What were the numbers 2 feet down?
I've been doing some reading and used to run ATI Blue + bulbs in combo with MH bulbs. I have to compare the spectral graphs from Geissman and ATI. I already have 2 Geissman bulbs and they are available locally. However, I may just order 3 ATI Blue+ and a Purple +. May be too blue for some folks but I'm a "blue" guy. I find the 20K look aesthetically pleasing. Not so motivated by rapid growth these days.
Numbers at the sandbed in the front of the tank about 110 par with new apogee software that autocorrects numbers. Despite turning down the lights, I'm still north of 300 par at my top center rock.
