2 Part Dosing

Nothing wrong with it that I know of. Just curious. Seems like such a small amount of sulphate to chloride.

I just looked at your link and see that it's his first/original recipe.

I see the error in my ways.
Mark in post #3 posted Randy's second, revised version of DIY supplements which advocates 5:3 as Mindy is suggesting. Mag chloride:mag sulphate
The next batch of Magnesium I mix up will be that ratio.

I use 7.25 cups mag chloride to .75 cups mag sulphate to one US gal.

I just bought some J&L shlobster magnesium chloride and on the back that is the recipe given to mix your magnesium.

Ok so according to J&L the powdered magnesium chloride and the flaked magnesium chloride are the same thing. Bought the flaked stuff and it dissolves fine and what not but was a pain in the butt to get flakes small enough to fit into the jugs small opening.

Ok still need a little help. My calcium is at 450 my alk is at 8 and magnesium is at 1350.

After checking my alk every day it turns out I am using .3 dkh every day. So according to the 2 part calculator I need to add 12ml a day of alk solution.

My only question is about water changes. I have about 55g of water in my system and do 5g water changes once a week. My salt usually mixes up around 10dkh. So what is the best way to keep alk at 8?

Should I dose a little less then needed so when I do my water changes it brings it back to 8?
