pool math

OK, so after I added the test results the top item is pH is below the ideal range". Then, when I go to pH is shows current reading of 7.4 and the "target" at 7.2 and thells me to LOWER the pH by adding acid. My question is why does it show a target of 7.2 when it also shows an ideal range of...

My second year (2021) of owning a pool and using Pool Math, I was able to export my results and it included when I added Chlorine (10% bleach) over the summer. This year I wanted to export my data from last year (2022) and the csv is not showing the additions of bleach, all my other stats are...

Or can it support a pool and a spa? At some point, I will likely convert my hydrogen peroxide pool to chlorine, but for now, my spa is regular chlorine, so I want to start using pool math as soon as I get the test kit.

Repeated steps below and it worked. Go figure. Hi. iPhone 24 here running OS 16.1.1 Hoped to open the pool today. Launched pool math. App crashes. Deleted app. Restarted phone. Downloaded app from App Store. Launched app. Said “Synching” for a while. App crashed. Tried reopening...

I have dark mode enabled on my phone (so that the menus, settings, theme, etc are dark), but most apps I override this to just be light mode. Pool math doesn't seem to have any option to override this and just uses whatever the system default is. I find it really hard to see what's on the...

Hi All, My pool is 17,415 gallons. 11 days ago my CYA was 42. Today I tested (at the store; I’m ordering my own test kit today) and it was 54. I’ve done a backwash, added water AND only added two Trichlor tablets in those 11 days. Can two Trichlor pucks add that much CYA in 11 days? Seems...

Our new pool is full and for the first two weeks we had a pool guy (sent by our builder) to keep the pool looking beautiful. Now, we have to keep up with the care and I decided to get the Taylor k-2006c test kit based on the information I found here. I performed my first tests today and found...

I'm a new spa owner following the How do I use Chlorine in my Spa (or pool)? approach to maintenance. I'm also using the Pool Math app to log my upkeep and calculate any chem additions. I recognize the app is mostly for pool use, but is it possible to change a setting somewhere so that the...

Hi friends, Just got a new liner and filled my 25,000 gallon pool I have a test kit and find that FC, TC, pH, are at the recommended level. But I have not added CYA. That level looks like 0 to me, as the black dot does not change. The Pool Math calculator seems to tell me to add 16 lbs. to my...

Hello, I’m new to using the Pool Math app. Is it normal that the app is saying the pH and Alkalinity is outside the ideal range even when it is within the target? I’m using Taylor K-2006 test kit. I’m using 12.5% Liquid Chlorine for daily sanitation and a Cal-Hypo powder for Shock. I decided...

It would be great if when entering in test results that were a notes field as well so that we don’t have to create two “separate entries” when really the notes are directly associated with the test results.

Hello, I’ve been enjoying this website and purchased the pool math app. It worked great for me last year, but this year it keeps the default values. If I enter my measured values the page changes and I can see what to add. But as soon as I leave that particular section, all my values revert back...

So usually about this time each year I export my prior year testing data from Pool Math to an Excel file. Worked like a charm, as usual. This year I'm trying to take my 2020 CSV file and send it back to populate my Pool Math App. I have the instructions from last year on how to do it; however...

I read in a previous thread that one can change the units used in PoolMath. I entered my hot tub's volume as 410 gallons based on the owner's manual, but would rather do measurements of additions with metric units - in part because measuring dry chemicals in grams and wet chemicals in mL is...

Greetings fellow TFP’ers, been a while since I posted but still here. I’m loving the Pool Math app, finally subscribed to it vs. just using the free version and the html version but just had one small suggestion that would help me, and possibly others, out tremendously. When you view the Logs...
