Can't you mix 3a and 3b together and run them on one channel?A minimum of 4 channels are required for the Base elements
You can but there is a risk of precipitation.
We have people who have combined 3A&B since day one (myself included) and never had a problem, however some have so the company line is to dose them as a 4 part.
IF you wanted to dose as a 3 part then it would be 3A&B with 8L of RO/DI to make a 10L solution, but you do it at your own risk.
