On the gravel, I used to say no, but since then I've learned that it makes no real difference. So yes, I would just run the siphon over the surface, don't dig in, to remove bits laying on the surface of the substrate. This helps to avoid overwhelming the bacteria initially.
It's been many years since I used Cycle and can't remember if it added a blue hue to the tank; I don't think so, but they may have changed it in the intervening 15 years since I last used it. Have any other substances gone in the tank, other than Cycle and water conditioner? And which conditioner?
