I would do so. Just not as much as the normal regiment. You could even just add a little pinch of the calcium dust into the prepared Pacman Food powder before adding the water. I've done this and the calcium mixes right in.
That's a really good idea Griff. I just bought 2 bags of the stuff and was wondering if it was safe to dust this food. If it was I was just gunna shake the ball around in my container like I normally do!
