Water treatment for wheat beer

[Martybhoy]

Hi, I'm brewing a hefeweizen next weekend, and would appreciate some help with water treatment. It's a 16ltr mash, 16ltr sparge, 2hr boil, and I'm expecting 20ltrs in the FV.

The grain bill is 3.4kg wheat malt and 1.5kg pilsner malt. Going by previous experience I'll be adding approx 100g-250g acidulated malt to hit 5.2pH.

Here's my water profile -

Calcium - 10.8 ppm
Magnesium - 0.5 ppm
Sodium - 4.8 ppm
Chloride - 7.5 ppm
Sulphate - 20.1
Hardness (CaCO3) - 7 ppm

Any advice welcome.

Thanks
