Calcium Carbonate

Two batches adjusted with this, still learning and fine tuning; very pleased.

Easy to find, easy to order, & BOOM! It was here @my door!
Thank you.

Works as should.disolves quickly.

Well, if you need to use calcium carbonate to adjust your water chemistry, you can use this without issue.

I live in Seattle. The water that comes out of the tap is essentially rain water. I like to brew English ales and Continental lagers so add calcium carbonate and / or salts and / or gypsum to my mash water on every batch.
