How to DIY Reef adv calcium and reef builder?

[nanomania]

Here are the details:

Reef Advantage Calcium[emoji769] also includes magnesium and strontium in amounts proportionate to typical utilization ratios (100:5:0.1, Ca:Mg:Sr).

Reef Builder:
Contains carbonate, bicarbonate, chloride, and sulfate salts of sodium, magnesium, calcium, strontium, and potassium. Each gram contains a minimum of 12 meq of alkalinity.
I want to make something similar, so i can do a 2 part dosing.

There are a bunch of DIY recipes for two parts floating around this forum that include these (I can't find the link right now). My DIY using Dowflake maintained all of these except strontium (I do not consider Sr important, but there is nothing wrong with adding it). Folks mostly now use other sources of calcium, so may be getting substantially less potassium and likely need to add it separately.

There are DIY recipes around. Assuming you have access to chemicals, I'd start with one of the two in the first post in this thread, and then we can calculate how much potassium and strontium to add to it:

FWIW, I presume you do not really want to DIY the exact products you posted, since they are not necessarily suitable for a two part. I don't think the ratios of the elements are appropriate, for example.
