You can mix this powders with RO water and then add it in this form. That's how I've been doing it for a long time now. Only problem is you need to shake or mix it every time.
Not familiar with auto dosing systems, but you can use Potassium (Bi)Carbonate to increase KH.
If the system automatically does water changes, that should take care of the normal gradually decreasing pH though?
No, I believe bicarbonates are generally more soluble than carbonates.
Bicarbonates tend to be more readily available than carbonates (not sure about pricing). With regards to the "potency" I did not work out the molar concentrations, but this is an exercise left to the reader (or you can just Google it).
Yes, baking sodium bicarbonate will decompose it into sodium carbonate.
Could you do the same, baking Potassium Bicarbonate to create Potassium Carbonate?
Again, I'm no chemist so I have no idea if anything is ignitable or if the same would apply (I would imagine so).
Too tired to read them right now, so will get back to that later.
Does it state anywhere the solubility of how many grams of bicarb vs carb can be dissolved in X amount of water?
Just from knowing that dissolved form would only be bicarbonates, wouldn't they have the same solubility?
Lol, I need to get some rest and research it.
There is no difference to dosing a freshwater tank vs a marine tank for KH maintenance, in a fundamental sense. You will certainly be dosing a lot less in most freshwater systems so that means use a less concentrated solution.
Ideally for a dosing pump, you want to be putting in small, daily amounts, matched to your consumption rate, to keep it as consistent as possible. So your solution concentration should keep this in mind.
Were you looking for someone to give you a favorable solution concentration and recipe?

The difference between potassium carbonate and bicarbonate is the pH you end up with. With potassium carbonate it will Be higher.
