I have an abundance of the other reagents and filters but no reagent a. Shipping issue…. How can I make for cheap? Image below shows it is 2 to 3% ammonium hydroxide. Can I just dilute something I buy on Amazon or from the grocery store? Any product recommendations? Why do other sections of the Hanna form say 32%, is that the threshold at which it is a hazard?
