Carbonate Clouding and Dust | Calcium Issues, pt. 2
Eric and Ryan explore various forms of calcium dust and clouding. They don't all happen for the same reasons, and the LSI tells the story.

Show Notes
00:00 - Intro
00:36 - Welcome to the team, Ryan Rickaby!
01:20 - Review of calcium hardness (amount of calcium carbonate) vs. LSI (saturation of calcium carbonate)
04:30 - Soda ash clouds the water instantly
12:10 - Sharing Eric's screen (alkalinity equilibrium), which can be found on the Orenda Blog, search for Alkalinity
14:21 - When the pH is high enough, carbonate ions (CO3- -) perfectly match with calcium ions (Ca++) to form calcium carbonate (CaCO3).
19:10 - If you put 11+ pH soda ash into the water, it will convert bicarbonate into carbonate, on top of the sodium carbonate you just added, which forces an LSI violation locally. So adding soda ash should be added slowly, and pre-dissolved.
19:56 - The cloud, it either gets filtered out, goes back into solution when the chemistry normalizes, or it precipitates out as dust.
20:27 - Plaster dust
26:52 - Carbonate clouding
30:12 - Winter dust
34:52 - Summary - Thanks for listening!
