Keep the MH lights, and swap the others with T5HO.
I find that SPS doesn't do well with just T5's (others might weigh in differently, but that's my finding).
As for wave motion, I have MP40W and find it's great for my needs. Hydor's are kind of bulky and the prop breaks easiliy. They don't have anything near of the output that the MP40 does. If you got the bucks go for MP40.
