First I am sure you do but do you cover your fermentor? If not it could be light that is part of your problem.4. You need to buy whatever it is needed to raise pH. katzke will tell you as I have no idea - my water is the opposite to yours! Have that on hand and after you add your grain to the mash and agitate it, use your pH strips and additive to get your mash to within 5.2 - 5.6 within say 5 minutes but don't be worried if it takes a lot longer. That's the part I need to figger out
Most beers stay in my primary for three weeks, come up the night before bottling to sit on the counter.
I suggest you look in your library and see what brewing books they have. I am sure it was Brewing Classic Styles that has some of the water profile info I am using. It is not complete and I found it in the back with the recipes but you need to pull it out. This is my starting point. I do some things others may not do but I had one real bad brew and one stuck ferment. After playing with my water my brews have been better so I will not go back.
So what I do is basically raise my Magnesium to the range of 15ppm. Raise the calcium to my target. Then play with the Sulfate/Chloride ratio for the flavor balance I am after. I will raise the Sodium based on the profile I got out of the book. I play with all of this till it is close and the Carbonate or Hardness is in the range I need for the beer. All of this I do in Brewater. I then enter the result into Palmers Excel spreadsheet I modified to allow Canning Salt as an addition. I may need to play with the numbers a bit to match my recipe color. I take the final numbers and convert them to grains as I have a reloading scale I use to weigh out the additions. My mash pH has been right on every time. I even had to add acid to my last brew just as predicted.
One thing I did was to enter your water profile into Palmers spreadsheet and it has a bit of an error in my mind. It says that your profile is on the Malty side. I do not think you have enough Chloride to make much difference based on what I have read but Pilsner water is low in numbers and the profile I have is even balanced at 1 to 1.

If you read all these you will know as much as I do about water for brewing. As you read you may find some do not exactly agree but that is part of the fun of discerning information.
