Switching to ro water

[sparky4056]

I have just recently set up my first dedicated shrimp tank.  Its currently housing about a dozen blood mary and half a dozen OEBT (all purchase from some of the members here).  I set it up using tap water, which is actually right on parameter wise, but have now decided to switch to ro because I would eventually like to keep a TB tank as well and figured I should get the routine down on some hardier shrimp first.

 

I'm just not sure how to switch it over without stressing the shrimp out.  Should I drain the tank and then reaclimate the shrimp or just do my future water changes with the ro?  Would doing an extra change a week to make the switch over quicker be too much?  Any help would be appreciated.

I have added RO water as a top off or a small water change as long as the parameters were very close, especially Ph.
