I decided to start using RO water and was following Gordon Strongs process in which he adds 1/4 tsp. phosphoric acid per 5 gallons to his brew water. This, according to him, should bring the ph down to about 5.2-5.3. I've now added 1tsp. and my ph is still around 6. I put a test strip in the phosphoric acid and it turned dark red so I know it's acidic!
Should I just keep adding more? Why would I need so much more?
