lowering ph in sugar mash

I have 50 gals of sugar mash with a ph of 8.4, how much citric acid is needed to lower to a ph of 5.2. Thanks


Two questions -- #1 - im concerned why your starting pH is so high.  What's the pH of your water? #2 -- there's no way to determine except to titrate a sample recalling that pH is a log scale so it will take 10x the quantity to get from 8.4 to 7.4 than 8.4 to 8.3.  


Sorry, New ph pen, forgot to calibrate, Thanks
