Additional LED?

You get what you pay for. Personally id get rid of both lights and buy some name brand ones. Thats just my 2 cents

Light it up ! LEDs are pretty direct there spred sucks . My LEDs light up my room. But I still can't grow any sps out of my 25x25 square .

I'm going to buy two hydras for my 48x24x20 tank

I think that light looks fine for growing SPS, I'd look at other things first.

I'd go for a bit more flow than those powerheads can do. Make sure temp is about 78/79, stable water parameters, not sure what you have for skimmer, but better skimming typically means better SPS growth.
Keep in mind that parmeters ideal for LPS aren't optimal for SPS.

But based on the brightness of the sand and hotspots on the upper rocks where the SPS are, I'd say you have more than enough light.

Overall though, long term stability is best for SPS

I'm planning on ordering the WP40 on Boxing Day and I have my Levites at about 60% I turned down blue so I can take better pic they normally at 70%. I'm using a euro reef 125 rs skimmer and my system is a high nutrient one. I stopped doing water test but last time I check my nitrate was 10-15ppm. I keep hearing about calcium reactors. Are they worth getting and how do they work? Do they cause tank crashes and what equipment do I need to buy to make them work?

full spectrum will give nicer color and definitely grow sps. But i reccomend 1 fixture for every 2x2 section as the d120s have lenses that focus the light so it will not spread near enough for a 4 footer. Or if you have your mind set on 1 fixture and are happy with that one you should do the same again as i wouldn't put a d120 on anything bigger then 30" (and that is with stripping the lenses off or changing them to 120 degrees).
