This is my first time treating the water - I measured the alkalinity as 220 ppm using the salifert kit, so I thought I'd reduce down to ~25 ppm. What a bloody palaver! I put the numbers in Graham's water calc and added the corresponding amount of CRS to my liquor. I tested the alkalinity again and it seems I added far too much CRS! I worked out how much extra water tap I needed, poured out the right amount of (now acidic) liquor, added some more tap water and got around 25ppm. I've just looked up the numbers on the brupaks website and the calculation from Graham's calc was spot on (I wasn't concerned about the accuracy of the calculator, I was worried that the CRS I'd bought was a different concentration or something). I'm still trying to think what actually went wrong.... I needed to remove and replace 8 litres of water from 36, so that seems like quite a big error! I must have made a dosy mistake somewhere along the way

Anyway, it's now mashed in at about 67 degrees with a little bit of gypsum. I checked the pH and it was somewhere around 5.2 or 5.3... everything seems to be back on track! I'm really hoping this will be a good one now I'm treating the water properly
