I use/run a m ix of LED's, for my DT a DIY broad spectrum array, on the fuge a DIY red/white/blue and on my Frag Tank currnetly running two Kessil A150WE's Ocean Blue/Sky Blue combination which replaced my Reef Radiance DM155e fixture for needed upgrade.
IMHO, if I were you and had some basic DIY skills would just update your current LED's to a better blend of emitters. You can order a decent selection of Bridgelux emitters from Reef Breeders for $1.50 ea and relly improve the overall spectral value quite cost effectively. If interested I would be happy to help with emitter layout and selection.
