Last night I put 200g of citric acid and 600ml of water in bottle A. In bottle B I put 200g of baking soda and 200ml of water. I shook them and put the caps on. I primed it by squeezing bottle A into bottle B. After about 30 min it was still not primed and was only half the pressure needed. I opened the cap and released the pressure and started again. It eventually built up pressure. I hooked it up to the diffuser and nothing. What did I do wrong?
