What is the best way to do an Awc on 2 separate tanks. I do realize I would need to set up a collective. I have a 240g fowlr and a 75g reef, the 240g I already have a cntrl4 starter kit and an awc hooked up with high & low level sensors with a waste pump and refill pump. Should I continue that method to the reef or should use a dual head dosing unit? Pros and cons of both.
