too much light?

[spikehs]

I just bought 2 400w ballast from venkiw for my 55 gal (36x18x18) I decided to go with the 400w cause there really wasn't that much diff and price + these will server me down the road when i upgrade to a bigger tank. I guess the question is (assuming I can keep heat under control) do you think 800w + actinics is too much for a tank (I want mostly sps). Thanks.
