Im not a lighting expert but I am the one who sold ya the light and I wasent aware you were honna put it over a 20 gallon tank,lol.Thats why I sold it in the first place.I had it over my 24 gallon ap but it was way overkill.I had to keep it like over a foot and a half away from the water .
If you cant find a use for it ill refund your money.Also did you recive the mounting hardware?
if your tank is 1' wide 8 to 10 inches should be fine but i would guarantee you will need at least a fan blowing over the top of your tank when the light is on....if you do not mind me jumping on this i was just wondering about this myself...how high would i have to put a 150w 14k on a 12g nano cube...
hagging a light 18" over a tank without a canopy does not serve it's purpose for me. your going to get too much light out of the tank. i think a 150 DE is more then good enough. and you can drop the light to 8" over the tank and not have as much of a heat issue and would serve it's purpose, lighting the tank, not your room. my 2cents
PICS?!FYI I run a 20g with a 150DE pendant. It's more than enough
