I started out with 150's. Although they were enough to keep things alive, coral growth and vigour was limited to say the least.
I then decided to go for the gusto and get 400's. After buying a dual 400 PFO fixture, I thought about it some more, and decided the 400's were overkill, and bought 2 - 250 Hamiltons. Brought them home, plugged them in, took a look at the tank. Unplugged them and put them in a box.
The 400's are there to stay until something better comes along.
