I am new to the doser world and have a Jebao Dp-4 auto doser that I need to set up. My question is with a 100g tank plus 20 gal sump mixed reef what should my starting numbers be? Right now I have brightwell aquatics solutions that I need to finish out but then I will more than likely switch to bulk reef supply stuff.
My params as of today are:
Alk 8.4
Cal 370 I am slowly getting this one up thinking maybe 420-430 range?
Mag 1400

I did a 15 gallon water change a few days ago so it put my mag and alk up higher than the cal

Well you need to know what the ppm is of the bright well stuff before knowing how much to dose

I tested daily to see what the tank was using up. Example Monday calc 440 Tuesday calc 435 Wednesday calc 430. Yes, I'm really simplifying this but the tank is using 5 ppm per day without dosing or water changes. I use the reef calculator on BRS to change from ppm to ml which tells me based on water volume what I need to dose daily. I would keep checking levels and with little tweaks you will be set in 2 to 4 weeks. I also use the jabeo dp4 and love it. I actually dose 4 to 8 times a day to reduce swings in levels. If you need any help I'm more than happy to help.
