I just set up a Cardiff 24. That's exactly the same as the Solana but with a bow front. I have the 150w HQI disco ball. So far I'm happy with it but its only been up for four days. In my 65 degree room the tank hits 80 at the end of a 12 hour photo period so I'm sensing a chiller in my future come summer.
The pump on the skimmer just has a plain impeller not a needle wheel. You should be able to do a mesh mod for improved performance. I just drilled six tiny holes in each impeller wheel. I can't say that that improved things since I have no reference point.
At my New Year's party last night it got a lot of admiration but then again there was a lot of wine involved. Only one person managed to get their sleeve wet when trying to see what a metal halide light bulb looks like up close.
Good luck.
