dosing ?

[donkey77]

Picked up a used doser with red sea a b c foundation powder, my par are
Ca 525-550
KH/alk 8.3 dkh
Mg 1550ppm
all done with salifert i know a little high, i will take readings for the next 4 days to see what my tank uses, its 100g system, i run carbon
Do i premix the powder into containers. How do i figure out how much iam setting the doser too

dosing is a bit of trial and error. As you already indicated though, you kinda have to determine (or guess) what your depletion rate is. Then once you figure that out you program your doser to replenish that. Your doser should have a dosing rate mentioned somewhere in the manual.

Also, those high values, are you getting those values before you've even started dosing or have you been dosing for a while now? Those are quite high values! You must be using some expensive high content salt or you are already dosing some of those elements ?
