dosing ?
 

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 ?

using instant ocean reef salt have not been dosing anything, did do a water change the day before

will do another test when i get home from work at 5

so do i just add this to some ro water in a jug, how much water iam i suppose to mix with the poweder, iam not a numbers guy

Here is a link to the manual for the ResSea Reef Foundation 1KG salts.

Page 9 is the info you are looking for.

new readings today
ca 550
KH/alk 8.3
Mg 1550
why are my par going up when i havent dose anthing yet, my alk is going higher should it be the other way around as in getting lower, i did change about 8gallons of fresh salt water 3 days ago, hmmm strange, will conti to test for the next 7-8 days, see where iam at

i still dont understand that can you check over my numbers
ok for the reef foundation A i need 9.2oz of powder, mix in with 3.8 pints of ro water, iam i reading that right
Foundation B 1.7oz of powder mix in with 21pints of ro water

more than likely a limitation to what the test can read , they arnt all that accurate in a pinpoint sense;)

if your trying to calculate your consumption dont do water changes while you are doing this.
