Jack, you knew Steve would try to sell you his girl lights, right? Listen to real reefers...go big or go home!! Besides, chillers are cool!

[Jack]

250 HQI DE setups are just way too expensive.

We'll see what I can do.

i have a chiller for you

[Jack]

Awesome. Thanks Aaron. Get in touch with me I don't have your #'s.

Is there a pretty good chance you'll need a chiller if you're running 400W? What advantage do you get running 400W's over 250W's if the k rating is the same?

What are you going to do with your old tank?

K rating has very little to do with anything other than esthetic's.
400W will produce more intense light further into the tank.

it also depends weather you are talking about a normal 250 watt or a HQI 250 watt. In my opinion depending on the bulb a 250 watt HQI set up will have more intensity than 90% of the 400 watt setups.

Steve, Can you show me proof that 90% of 250's have more intensity then 400's ? I have yet to read any data that states this. Only that for the slight increase the 400's offer 250's are a energy wise choice.
