Thank you, I just pour 2&1/4 cup of arm&hammer baking soda on sheet, in oven for 1hr, @ 300%.

I’ m completely sure it is sodium sulfate anhydrous.
I’ll prepare the solution again with only sodium hydroxide and check the pH effect again.
Thank you Randy. I'll do as soon as I get new resultsOk, let us know what you find. [emoji3]
Sorry for dusting off this old post, but that 1000 : 9 ratio sounds a lot like the 10.28 : 0.0906 mM ratio found in NSW (Pilson, 1998). Are there studies that show that strontium is incorporated at that rate, or is there just an assumption that it is incorporated at the NSW ratio rate? (Asking for a friend.)Since it came up in another thread today...
If you want to add strontium to a DIY two part, here's a rough recipe.
Corals have about 1000 calcium ions for each 9 strontium ions when grown in NSW. Too add about that much to a two part, put in about 1.3 % as much strontium chloride as calcium chloride.
No method can perfectly balance Sr since the demand is about linear with concentration. So your tank will use twice as much Sr (per unit of alk or calcium consumed) at 10 ppm Sr++ as at 5 ppm Sr++.

I prepared fresh two-part solutions, the two of them, and both at 2x strength. They are working great and the pH effect has balanced the absence of the kalkwasser. Basically, I get a better pH swing by using the new two-part formula than the old one with kalkwasser. Actually better than using Seachem Reef Fusion together with the Aqua Medic kalkwasser reactor. Therefore, better pH, and alkalinity, calcium and magnesium stability at a fraction of the cost in terms of money and effort.
Thanks Randy!!
I really appreciate you Randy!FYI, food grade sodium sulfate is available online and is not expensive:
https://www.amazon.com/Natural-Sulfate-Granular-Anhydrous-Crystals/dp/B00L4L73CM
Using it helps keep the recipe from skewing the chloride to sulfate ratio in the aquarium.
You rock and that's' :104 deg for non metric folks...In part 2 of the old reciepe, you have sodium carbonate. I always end up with undissolved Sodium carbonate. So, around 40C is the magic temperature for maximum solubility. I was going higher than that.
