instead of using b ionic's part 1 for alk and part 2 for calcium, couldent i just get a gallon container and fill it with ro water then add some baking soda and use that for part one, then get another container with ro water then add kalkwaser and vinager wich would be part 2 . its getting to expensive to keep up with the b ionic solution's at 30.00 dollars a bottle.my system , mostly sps is consuming about 60 ml a day of each componet wich leaves my tank readings at dkh 10.2 and ca 350, ph 8.25 and8.35 at peak, total gallons is about 225. 8O
