I currently have a jebeo 3 channel doser that i use for cal and alk addition. I have it set to dose 24 times a day for both. Problem i have is my up take of alk is higher during the day and would like to have more ml added during that time. Is there a doser out there that will allow me to change the amount dosed during day compared to night? Im trying to get my alk as stable as possible.
