I may be wrong, but I don't think it will take seachel's tank that long to cycle, probably less than a week, but to determine this for sure is just to check the water parameters. If there is no ammonia, nitrite, or nitrates, the tank should be cycled and ready. The live rock doesn't need to cure...it was already cured and alive, the bacteria would just need to multiply enough to handle the excess nutrients in the water, which the bacteria multiply quite fast and this would be done within a day or so. As far as lighting, there are several people who keep SPS under T-5 lights. It is not the amount of wattage into the tank, but rather the available PAR. I would imagine the lighting would be enough for the clam and if it was in question she could always position the clam up near the top of the water column. I kept my first clam under PC lighting and it not only survived but grew.
As far as dosing...it is definitely not rocket science and using test kits...makes it pretty easy.
I'm sure she could have figured these things out. Just my thoughts.
