Slamming and stains.

Is there a way to slam without causing the iron to fall out of solution?
Probably not. Depends On the iron level at the time of SLAM. Regardless, we must always kill the algae first via the SLAM Process before treating for iron. What I would recommend though is having polyfill available (skimmer filtering) so that when you do increase the FC to SLAM level, if the iron precipitates-out you will have a better chance of capturing it. Save any Magic Jack's for after the SLAM Process.
