Changing ideal and recommended values in Poolmath

[Prospectwi]

Is it possible to change recommended and ideal values in Poolmath?
Thanks!

Welcome to the forum!
No.
I suggest you read ABC's of Pool Water Chemistry.

First and foremost, WELCOME TO TFP!

As Marty mentioned altering the suggested levels is not (currently) supported. Is there a certain item we can further explain why we suggest as we do?

Would be nice to be able to change recommended values. For example, "The ABC's of Pool Water Chemistry" you refer to says 50-90 for TA which seems to be the value the app uses. However, the Taylor test kit recommends 80-120 for TA which is further supported by other articles on the web. One of which states, "It is best kept in the range of 80-120 ppm. When the total alkalinity value is less than 80 ppm, the water can become aggressive and the pH can swing easily upward and downward and back again. If the value is higher than 120 ppm the water can become cloudy and scale forming and the pH will tend to drift upward."
So who do I trust? It would really be nice for the app end user to determine their own source of truth on these values. That is, unless I'm missing something.

The app is designed to help people follow the TFP pool care process, it’s not a generic app. So that’s why it wouldn’t be good to allow it to be changed.

That said, take a look through the articles here on why there’s a difference. You’ll find that TFP does not advocate for using trichlor pucks for regular chlorine additions like so many websites advocate for because they increase the CYA so high and drive the pH down. The higher TA recommendation comes from that to counteract the pH decrease caused by the trichlor. By using liquid chlorine which doesn’t add CYA or drive the pH down, you can maintain a lower TA which helps with pH stability.

Having been through the cycle with all the other sources of truth, I trust TFP. Why? Because you can find all the chemistry and foundation/rationale to the recommendations in Pool Care Basics and The Wiki

Here are some examples on TA and more importantly the "WHY?"

Thought about this question some more. Here are two threads on why you should believe...

Featured - How and why did you find TFP?

I thought it'd be fun to share what initially brought you to TFP and how you found it. I'll share. i bought a house with my first pool. I previously had an above ground pool but had no idea how to properly care for it. The prior owner left an old TF100 test kit that had expired many years...

How Clear is TFP Clear? Let's See (Pics Only Please).

How clear should my water be? A very common question. Here is mine on a calm morning where I could finally vacuum. Yes I know, I'm still manually vacuuming. It took me 7 years to finally get an SWG, I'm working on a robot. :) So now let's see your water clarity.
