youre using 2 150s over a 20 and it isnt bright enough? dang.
sps is my current focus. though i would cater the tank to whatever animals would be suitable.
your opinion/experience of the 150DE seems to be quite contrary to what i have been reading.
any pics?
at such a low wattage i definitely wouldnt be using 20k. besides the lower par, i prefer a more whiteish light.
i was interested in 150W DE AB10k... they are supposed to be the iwasaki's of the 150W DE world, just not as yellow!
and i have heard good things about the geismann 13k megachrome bulb as well.
