Put metal halides on your tank, and the light would come on. :-)

Forgive your enemies. But always remember who they are.

Depends, but usually, yes.

However, I had 130 watts of CF lighting over my 20gal nano. Could not
get the temp below 82 during the day. Just replaced the CF's with a
single 150watt MH, and the temp is staying EXACTLY the same. (82 degrees)

From everything I have heard or read, this is too high. But Everything
seems healthy enough even at that temp. Algea is a bit of a problem,
but no real biggie - ceriths and a conch take care of that well enough -
it doesn't get TOO out of hand.

At this temp, my derasa has been growing at a rate that seems VERY fast
to me - it added like and inch or so to it's shell in 3 months time.
Ditto for my zooanthids - number of polyps has doubled in the last three
months.
