I'm about to place an order for a LED Fixture & your controllable unit seems perfect but i have 2 questions. 1.I have a 120gallon 48x24x24 reef tank & I would like to have to option to keep high light required sps coral. Will I be more suited for 2-16" fixtures w/90deg optics OR squeeze 2-24" fixtures with 60deg optics? 2.I just recently purchased a Apex controller & want this to control the different color combo's & timers. How much would it be to add this option or is it even possible with your multi color fixtures?
