Which ones are the right ones?

[billdogg]

As the title asks - which do I get?

My sister is CFO of a good sized chemical company, and through her, I can purchase the various chemicals needed for the BRS solutions, and at a price that makes it worth the effort to figure this out.

Any help anyone can offer (Randy???) is greatly appreciated!!!!!


For the Calcium additive:

I don't know how much this will help, but I mix up my calcium using food grade Calcium chloride anhydrous. Same stuff they use to wash produce, especially apples. Just be careful when mixing with RO because the reaction is exothermic.

Alkalinity is made of food grade Sodium bicarbonate. Not sure which will work best for you.

As far as magnesium goes, all mixtures that I have used fowled to quickly to be useable. So I would be interested in this as well.

I can't see any of those being an issue. The only thing to watch for is that different hydration numbers will require different amounts to get the same concentration.

That's my dilemma. I want to get dry chemicals and mix them in the same manner as with the BRS additives, so any that are in solution already are out. That still leaves several choices for each. I'd sure hate to nuke my tank in an attempt to save a few $$$!

 

[disc1]

Oh, none of that is going to nuke your tank.

In Randy's recipes, the calcium chloride is dihydrate and the mag sulfate is heptahydrate and the mag chloride is hexahydrate.

The sodium carbonate he has you baking off yourself, so we can assume that would be (nearly) anhydrous.

Thanks for the help!
