No. You need to use the GHL doser. The ION Director communicates with the doser so...This may be a stupid question, but could you use a different brand’s dosing pump for the ion director? I have a 4 head versa pump and I’m only using 1 of the pumps. I’m curious if I could just order the ion director or if I’d need their pumps to go with it. Thanks!! This looks amazing!
