Understanding Borates
The Orenda App 3.0 includes borates as an option on the Orenda Calculator. Eric and Jarred dive deep into borate chemistry, and how borates buffer pH, impact other chemistries, and how they impact the LSI. This episode contains nerdy talk.

Show Notes
00:00 - Another long intro, reminding listeners about Swim Across America, and WU C3611 at the Int'l Pool & Spa show in Vegas this November.
03:34 - Orenda is neither pro-borate, nor anti-borate. We don't find them necessary, but we don't criticize those who use them responsibly either.
05:41 - Never exceed 50 ppm borate in your water, for toxicity reasons.
07:46 - What are borates?
08:49 - Bicarbonate/carbonate alkalinity and its pKa value of 6.14 pH.
09:52 - Boric acid/Borate and its pKa value of 9.2 pH.
11:22 - Borates buffer against the rise in pH by taking a hydroxyl ion (OH-). This is the opposite of what bicarbonate alkalinity does.
13:05 - Borate algaestat claims
13:52 - Borate water clarity claims
14:40 - Borate toxicity and availabiliy in California
15:40 - Use properly labeled products for their intended use
17:15 - Why borates are in the Orenda App? They impact the LSI.
18:10 - Summary. Thanks for listening!
