Hello! Long time follower of the TFP way, and I love the PoolMath app, both on the desktop and the phone! I was just wondering if it is possible to modify anything manually in the app? The reason I ask is that the liquid stabilizer I buy, I use the Natural Chemistry brand, is 32 ppm per gallon in 10,000 gallons, but the app seems uses 37. Is there a config file or something somewhere that can be edited by the end user to change that value?
It isn't even really that big of a deal, but every time I add my stabilizer after a hard rain, I think about it.
Thanks again to the devs of the app and everyone at TFP who have created such a supportive community and has made my first year of pool ownership less stressful!
 
I wonder if this is one of those instances where the manufacturer reduces the percentage of “active chemical” but increases the percentage of water as a way to save some cash. Rather than charge more…..water down the product. 🤔

Let me do some reading and check other brands out there……wonder if they’re all coming up wrong now?

I thought about making a dilution to check the veracity of what is on the label but I haven't found/taken the time to do it since it is such a small thing. I can say, using 32 ppm from the bottle in my calculations results in subsequent tests that are pretty close (as close as that visual test in the kit can be) and I don't trust any of the pool stores here to be well calibrated enough to verify it.

Thank you for the replies!
