Personally, I wouldn't crystallize at all.  But I am one of those stone pros who is anti-crystallizer.  I would hone it, get rid of all that crystallizer as best as possible, use AquaMix Ef-ex to clean and treat the efflorescence and hone/polish it naturally and seal with a water-based impregnating sealer. If the efflorescence is seriously bad, I would of course still get rid of that crystallizer because you need to get to the stone itself, use a careful solution of water and muratic acid, then clean it with an akaline and then a neutral cleaner, then apply a water-based impregnating sealer and detail butt with hogs hair pad. The stone needs to breath and crystallizer won't allow it to do it...plus all that moisture that is creating the efflorescence should be allowed to properly evaporate to try to help minimize it.  Can't always guarantee the removal of efflorescence.  But the Aqua-mix product can now be purchased from many Home Depots and we have loved it. 

Just my two cents

Dayron,
If the floor just started showing signs efflorescence in the past 5 year and
the stone has been crystallized the crystallization could be blocking the
stone from breathing. This causing the moisture to collect and then push
through the crystallization. You need to hone 220 open the floor and allow
to totally dry. If for a couple of days. If you are going to polish then
polish with 5X and allow the stone to dry. It will probably effloresce
again. When it does buff off with a dry steel wool pad. The floor will
continue to effloresce until the stone and the sub straight dries totally.
There not going to be any quick cure.
