I am so glad I found Orenda! You're really helping me understand all about pool water. I've been using the app for the last 2 months since I decided to stop my pool service and it's never looked better. It's amazing how much of a difference I get between my readings and what the pool place gets. I like to go there to see what they're getting. I was using them as a baseline, now I'm just going by what the app says to add to the water and like I said it's never been better. A few weeks ago they told me to add a gallon of muratic acid and I'm thinking that seems like way too much. The app said 17 ounces...I added 17 ounces. I'm sure that was a wise decision. Anyway, thanks for all your great knowledge, it's appreciated.
I noticed on the calculator that the lowest temperature only goes to 32 Will there be a update for lower water temperature (new England area) only asking want to treat water for lower Temps for closing season
Hi Guys, So I have an question about TDS and how it relates to LSI. So let's say I have a SWG and during the summer my pool is 82 degrees and TDS including salt is around 3500. I get my water balanced and it's a thing of beauty. Being in the North East, I can try to forecast for future temp drop from 80s to 30s. Obviously drop in water temp decreases LSI. So during winterization I can increase PH, Alkalinity or Calcium to anticipate for that drop in water temp and compensate accordingly using the Orenda app. However, as the temp drops the salt will be much less dissolved thus bringing down TDS as well. And i have no idea what TDS will be at 40 degrees. Should I even be concerned about it or just plug in TDS as it is currently is and just adjust PH, Alkalinity or Calcium higher? Do you recommend one over others to be adjusted higher for that anticipated temp drop. Thank you.
Very well thought-out question Erik! But actually your salinity should not decrease at lower temperatures at any noticeable level (if at all). This is often misunderstood because TESTING for TDS tends to be skewed when the water sample is cold. So use the current TDS throughout the winter, load up on calcium hardness to prepare for rain/snow dilution and cold water, and keep doing what you’re doing. If you have more questions, email eric@orendatech.com. Cheers
Excellent episode. I disagree with water line/spillway scale being totally driven by LSI. I agree with those people that feel it's mostly based on evaporation/wicking. Aqua magazine currently has an article on this subject. Keep up the good work 👍 aquamagazine.com/pools/scale-does-tile-an-injustice.html?eid=354660084&bid=2672919
Yes the tile line does have a lot to do with evaporation, but if you think about it, that’s still an LSI issue. So you’re not wrong, it’s not totally LSI. BUT evaporation reduces water, which increases the concentrations of calcium and alkalinity, therefore precipitating calcium carbonate easier. Another issue is scum lines from organics, which float to the top of the water and get stuck on the tile. The organics make it more difficult to remove the scale line.

We are so pleased that it’s working and our work is valuable to you and your pool. Thanks for listening!

Correct, because at 32 water freezes.

I prefer you guys using cartoon to explain it. like MIT is doing with D.O and Temp. Sorry, i am more visual than listener.
We prefer cartoons too. Do you know any illustrators?
