I have been running LEDs since I started my tank which is for a year now. I mostly have SPS. All nutrients have been under control. Stable alkalinity, calcium and magnesium but unimpressed with the growth until I added two T5 bulbs retrofit and have had them on for about two months and have already noticed significant growth as compared to LEDs alone. I finally feel like I can have a thriving SPS tank after a few years with this growth rate. Just thought I would share, I thought I was doing something wrong.
