I am making my summer lagers right now and will stop to brew ales in May. I have been using the PseudoBohPils water pprofile from Bru'n Water. Can I keep the same water profile for a Kolsch?

You can use the same BoPils, or if you want to add a little more minerals that would be fine too.  FWIW, my tap water is moderately hard, and for the Kolsch that I just made, I just used my tap water without any adjustments, and I think it turned out pretty well (although it isn't carbonated yet).

Can you be a little more specific in what minerals to add?

It depends on your source water

It depends on your source water

...and depends on whether you think it really matters, and how much it takes to make a difference.  On that, I honestly (1) don't know and (2) don't know.  Just being honest.  Best advice: Experiment over several batches to find out what YOU think is best.

I use 100% RO water.

The psuedopils profile doesn't have much sulfate. Koln water does have a decent amount. Roughly 70 ppm sulfate and 35 ppm chloride. Sulfate doesn't make beers bitter, it makes them dryer.
