yes, the white is daylight and the blue actinic. did you check that nano tuners link i posted for lighting upgrades?
i'm not sure how to answer the light strength ratings question for you, except to say that corals use photosynthetically active radiation
, or PAR for photosynthesis. this is present in all artificial lighting, but in some more than others. years ago, they used to use compact florescent lighting over reef tanks, but recently they've discovered many more powerful solutions. they noticed that the CF
fixtures didn't penetrate the water like some other types.
many aquarium lighting manufacturers still sell cf
fixtures, but they are being phased out.
your system will definitely support a good amount of corals, but i'm just not sure about things like stony corals, clams, or anemones.
metal halide, T5 high output, and the new LED
lighting are much more potent than the CF
. to know for sure what kind of PAR your unit puts out you would need a PAR meter. it's a roughly 300 dollar device. otherwise, you can just "listen" to your livestock. if you see them losing color or turning brown, then you know you need more light.
