I suggest using a brewing water calculator to help you figure out what minerals or acids to use and how much of each. Hopefully you have a precision scale so that you can measure out the typically small amounts of each mineral.
Do you know the balance of your water?
I would suggest EZ Water Calc for starters, it's basic and easy to understand.
I've never had any luck with Bru'n Water, it's always been well off specifically with mash pH (sorry Martin). Mash pH is more critical than the majority of additions IMO, and because of that, I cannot afford to use Bru'n Water.

Have a look at this thread here by @strange-steve . I would got for something like 50ppm of calcium chloride and 25ppm of gypsum which equates to 0.19g per litre of calcium chloride and 0.09g per litre of gypum. Would be suitable for a NEIPA style beer. I just made a hoppy wheat with the same additions. You could go for 100ppm of gypsum if you want the hops to cut through. My advice would be to read that thread and see if you can get your head around it. I only brew with RO and its really helped me out. Hope that makes sense, if not ask away. Plenty on here know more about it than me.

Yeah thanks .. Ive looked at the calculator.. looks v good .. when it says add at mash , is that onviously when it is in the early stages of mashing ... and adding to boiler , is that when afer mashing, youve drained it off, and you boil it up for an hour or so?? cheers Robin

You want the mash water all treated before you add any grains to the water.
With sparge water you have two choices.
1. Treat with pH adjusting chemical and all mineral additions.
2. Treat with pH adjusting chemical and add minerals direct to the wort before you boil it.
