It's likely due to a shift in the spectrum, as well as more energy, as mentioned above. You could siphon it, but I wouldn't worry too much about it. A reef tank is a dynamic enironment, and will blanace itself out as long as parameters are maintained. Your levels look fine, maybe test PO4 as well, but I bet it's gone in a week or two.
