Nothing keeps corals alive and happy more than patience and knowledge. If you must stock corals in the near future start with softies.
I agree with the above. A 100 gallon tank should IMO
have in general about 200 watts of LED
for softies, 300 or better for SPS
. Lensing makes a big difference in penetration and PAR levels on the sand bed. 2, 3 or 4 watt LED
emitters are all okay as long as the total wattage adds up to the minimum needed. Dimming drivers (PCM) are nice. It is up to you as to the mix of white and royal blue LEDs, I prefer 2/3 20K white and 1/3 royal blue (540nm). But many like the opposite, for a more blue florescent look.
The last light I built, there is a thread, used the new multi segmented LED
chips that come in 5-100 watt sizes. My son used RapidLED on his build, but I tend to just order components as needed off of EBay.
