So I have 2 XR15 pros hanging over my red sea reefer 350 (47l * 20w * 21h) using their RMS arms. I have been trying to keep SPS but having a very hard time. Alkalinity is stable around 7.8~7.9 and calcium around 435. Nitrates are 1~2 and phosphates are 0.05.
1. Par - I measured PAR at about 206 under the light where the highest SPS is being kept at the moment with as low as 50 between the two lights about half way down the tank, and about 70~100 par on the sand bed. What PAR are fellow SPS keepers keeping their tank at and do you consider what I have decent? Should I go higher/lower/add new fixtures?
2. Night Light - I saw ecotech has a feature where if you leave the lights on at low % overnight they increase/reduce the light output based on the moon phases. Does anyone use this and what light %s do you run at? Is this even a good idea to run a light overnight?
3. Spectrum - I currently use the AB+ profile with more whites turned on to make it easier on the eyes. I was wondering what other profiles people use to light their tank as a reference. Or what people recommended as well.
I would also appreciate any sort of advice for lighting with LEDs in general, thanks in advanced.
