Hi all,
I have 142g tank 59"x23"x23".
Light- 2 bulbs metal halide 150w each, 6500k both.
Co2 (indicator- light green always), 6h photoperiod, EI ferts.
I had some algae but that's because I was setup the lights to close to the surface couple of weeks ago.
Now, the lights are about 13" above the surface.
still have some algae...
Someone has experience with MH and can tell me how much inch above the water surface I should setup the light?
