need your advice please

Hi, I am thinking to change my lighting system to 8 x 54w T5 or 6 x 54w T5. Now I have 2 x 175w MH and 4 x 96w tube lights. My tank is 90G mixed reef tank.

and also changing wave motion device to single Vortech MP40w Es or 2 x Hydor Koralia 4 Controllable Powerhead and Hydor Korlia Wavemaker Controller (2 Pump). I realy like MP 40w ES but if I need two of them then it quite expensive and I am not able to afford them. I also like Hydor Koralia, too and I guss price is right. single MP40w ES price is 2 powerhead plus wavemaker controller. Are they making wave like MP40? Could you please give some your valuable advise.

Thank you
