Where to buy sodium hydroxide?

[Gribbles]

Title says it all. Looking at and comparing options to maintain alkalinity while raising pH as best I can.

I usually shop from BRS but no options there. I'm not sure I can trust Amazon. My system doesn't really consume much calcium above what water changes provide so I don't think/know if kalk is an option.

Regarding shipping, I live in the continental US.

Can I ask, do you just follow Randy's recipe from here?

No, I mix my own strength such that a defined volume translates to a simple multiple of alkalinity. For example, my current lower strength solution doses my water volume with 0.2 alkalinity for 40 mL.
