It'll be over my 24x24x20 cube. Both fixtures have 4xT5 (main reason why I'm considering the change are the actinics themselves... this lead to finding some nice fixtures).

I would go with 250 watt. A 400watt might heat up your tank a bit too much and I don't think it is necessary with 20" high to have more than 250 watt. I have 250 watt and have very good results with my SPS, even in the middle of the tank and mine is 24". The fact that I have 250 watt also let me put some zoanthids at the bottom without burning them up.

It's only 20" high? Definitely save yourself 150w, 250w will be fine.

Thanks guys. I was already leaning that direction (already have 250W) but have never used 400W SE before, so I was curious.
