Id like to start dosing 2 part. I been testing my cal, alk, mag daily. Yesterday: Cal 410, Alk 8.4, Mag 1350.... Today: Cal 390, Alk 7.6, Mag 1350. I have 2 part from BRS mixed up in gal jugs like their video shows. Its calcium chloride and soda ash. Today I set my doser up and dosed 10ml of Alk solution into my sump. It immediately turned white and precipitated to the bottom. What did I do wrong? Am I missing something? I turned my doser off.
