Would it be ok to add the AF salt once a day if I am dosing the other parts multiple times a day? I have a 4 head doser and need to dose all 3 parts plus nitrate and phosphate. I was thinking the AF salt would be the best one to do a one-time dose.
I'm using potassium phosphate and Nitrate. Can either of those be added to part a or part b
I keep meaning to go back through all of this and may have questions.
My goal is to get away from Triton due to cost. I want to make sure I understand how to get this setup for balanced 1:1:1 dosing for Alk/Ca/Mg and A,K C and of that means mixing those in or adding another dosing head or two.
Here is what just made my head fall off. If all of that is correct, then anyone dosing magnesium as a combination of magnesium chloride and magnesium sulfate doesn't need par C, they are "balling" because their much larger does of Mg already have enough to restore ionic balance, and add Mg.
Why buy part C instead of just doing magnesium at the proper consumption rate, plus a pinch of it makes you feel better. So most systems are "balling" if they are 3 part, even if there is not an explicit "NaCl free" separate component.
This begs a further question that I think maybe only Hans-Werner can answer. Why not just publish the recipe is balanced Alk:Ca:Mg in the first place then? Maybe because he doesn't see magnesium consumption fixed diretly to the alk and calcium consumption?
Is this wrong? Have I lost my marbles?
So, am I correct that the key is knowing the potassium and other minor ions in Part C, and assuming that A and K do not cover those?It is correct that Part C is “mostly” mag sulfate and chloride. That is why many folks have been successful with my diy using mag chloride and sulfate as the third part.
But there are important other ions in Part C that will get depressed significantly and detrimentally if they are not maintained somehow. Potassium is a big one. Others may include bromide, fluoride, boron, and more. Part C adds and maintains those against the salinity effect.
If I understand you correctly, ESV does what you suggest: essentially put everything in 2 parts instead of 3.

With a bit of work I could make a three part Alk/Mag/C plus A and K — where C is magnesium sulfate and chloride in sufficient quantity to cover the ionic imbalance and daily consumption. Adding potassium, bromide, fluoride, and boron for better balance. I would assume these minor elements are at the ratio of NSW or does more stoichiometry (ick) needs to be done?
Or easier and more costly. simply, purchase Part C and combine it with DIY balanced magnesium sulfate and chloride, minus whatever magnesium is already present in Part C.
I guess the true question becomes, in your estimation, how important are the minor additions of "bromide, fluoride, boron, and more" to part C.
So in the reverse:Part C is purely a salinity correction product. It is literally a salt mix without added sodium chloride.
A and K is a consumption offset product.
They fix different problems with different sets of ions and there is no reason the use of one will alter the use of the other. There is no need to be concerned about overlap, and in reality, everything in A and K is in Part C.
