00:00 - Intro

01:43 - Swimming is an individual sport AND a team sport. Individual athletes racing the clock are part of a bigger team. This translates to pool companies as well.

04:02 - Let's focus on people. Not the job, not the skills, the people. People are always the most important aspect of a business.

04:32 - The benefits of a baseline, such as water chemistry minimums. Standards lead to collective intelligence, the team becomes more cohesive.

10:09 - Build a family and team atmosphere. Gather input from employees. They know things you do not.

10:45 - A reward system within the team, i.e. "Mojo" the monkey.

13:41 - Involve the homeowners in appreciation of your employees too. Example: Southwest Airlines 'kick-tails'

17:47 - With more profitability comes opportunities to clean up the brand. Better uniforms, cleaning the trucks, etc. Everyone wants to take pride in their work.

19:25 - Increasing the margin for error also helps keep employees. Example: customer adopted the Orenda program and noticed their employees were starting with some 'early wins' and getting compliments early on. More room for error means less frustration when learning.

23:24 - Training is available all over the place. Orenda has Orenda Academy, this podcast, over 100 blogs, videos and procedures too. But other companies do too. Manufacturers want to train your people.

24:15 - Summary: Let your team build a healthy culture, once you have established a baseline and a family/team atmosphere.

00:00 - Intro

01:44 - Drinks made from plants have natural color from Tannins. Wine, coffee, tea, etc.

06:10 - Nothing replaces the importance of physically cleaning organics out of the pool. Leaves, acorns and other droppings will overwhelm chlorine if you do not regularly remove them.

10:25 - Tannins can be soaked out of decaying organics. They either stain the surface or discolor the water, or both.

12:48 - If you don't clean off mesh covers, decaying organics will release tannins into the pool below the cover. It's not pretty.

14:20 - Cleaning up tannin stains and discoloration mostly involves chlorination. But is chlorination the most efficient way of handling tannins? Not in our opinion.

15:58 - CV-600 and CV-700 enzymes are awesome for handling tannins. Enzymes devour them.

19:05 - How can you identify if it's an organic or metal issue?  You can do the white bucket test. Scoop some water into the clean white bucket and add a bit of liquid chlorine.  If it clears up, it was either algae or tannins (organics). If the water gets darker, it's metals.

21:03 - Summary. Thanks for listening! If you have questions or requests: podcast@orendatech.com

00:00 - Intro

01:49 - Most people mistake this problem for scale. But it's not scale.

05:05 - This is a chemistry issue, not specific to brand of finish or pigment. This is not a cement or pigment failure, it's a water chemistry problem that can be prevented.

06:01 - How this occurs during plaster application, exposure and startup.

15:36 - How this occurs months or years later,  from aggressive water over time.

21:04 - When we get calls about these issues, the answer is not always good news. We are not in the business of pointing fingers at who caused what.

25:45 - Two causes of etching: not diluting acid, and using trichlor feeders, especially on pools with auto covers.

28:35 - Summary. Thanks for listening!

00:00 - Intro

04:18 - Calcite crystals are not the same thing as scale

10:49 - Jarred describes photos of crystals

14:18 - Jarred explains how to prevent crystals, and explains it better than Eric. Well done, Jarred.

25:16 - We know of 4 types of crystals. Each has a different difficulty of removal.

32:35 - Jarred summarizes, and summarizes better than Eric. Now you're just showing off, Jarred.

00:00 - Intro

02:00 - Look up "nodule" on blog.orendatech.com, and you will find articles that show photos of calcium nodules. You can also do an online search of nodules and find plenty of information.

04:32 - This is the Orenda podcast, and we believe you should hear both opinions on nodules.  First, the NPC's position.

08:08 - Now, the onBalance position.

12:42 - Both sides acknowledge nodules are not scale. They are minerals from within (or behind) the plaster surface that come to the surface.

17:12 - Water chemistry itself cannot stop nodules once they've started. They are not chemistry problems, in our experience. They are a physical problem with structural weaknesses in cement.

20:12 - Summary - thanks for listening! If you have comments or requests for the show, our new email address is podcast@orendatech.com.

Swim Across America | Team Orenda: https://www.swimacrossamerica.org/goto/orenda

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!

00:00 - Intro

01:57 - Definition of scale: Scale is the hardened deposit of a calcium compound that has precipitated out of solution. 

02:30 - Analogy of sugar in a drink. This analogy explains the difference between the saturation of calcium carbonate (LSI), and the amount of calcium carbonate (calcium hardness). 

06:33 - Calcium carbonate (CaCO3) is the most common form of scale, by far. But there are other forms of scale: calcium silica, calcium sulfate, calcium phosphate, and probably some other obscure ones we have yet to encounter. They are more difficult to deal with.

12:35 - The same amount of 'sugar' (calcium carbonate) can be too much, too little, or just right, depending on other factors in the LSI. The key here is that scale falls out of solution when the water is oversaturated. Carbonate scale occurs over +0.30 LSI.

16:10 - When you see scale in your pool, it will always be in the hottest places first. In the case of carbonate scale, it will be in the highest-LSI areas first. Primarily a salt cell or heater. Flakes in salt cells occur because of a localized LSI violation in the salt cell.

22:08 - If scale is not on plastic fittings, the face of tile, lights, etc., it's not scale. It must have come from the cement, not the water.

25:46 - To chelate or sequester, the water needs to be warm enough (~65ºF or warmer), or else the chemicals will not activate. The warmer the water, the faster these chemicals work.

29:06 - How to remove scale

32:28 - Summary. Thanks for listening! Stay tuned for the next four episodes in this series of calcium issues.
