So I made the switch to run AF 1,2,3+ over brs 2 part about 1-2 months ago. I'm currently making my own 1,2,3 components using AF guidelines but I find myself having to dose twice as much ml/hr as compared to the brs solution. My question is.... are both alk and cal supplements the same minus the strong components (a,b,c & k) that AF uses? Can I add the strong components to the brs cal and alk without a problem? I'm looking to go back to brs 2 part (alk & cal) because it mixes better/faster, only have to dos 160ml instead of 320ml and clear jugs. Taking all suggestions/advice.
