Pool Math App Ideal Ranges

I have a mineral pool (FROG system) and the app is always yelling at my that I am out of the ideal chlorine range. Is there a way to edit the ideal ranges? If so, I can't seem to find it.

Any help is appreciated.

Thanks!

Interesting feedback. The pool company really likes the frog and has had good success. My CYA is currently 45 and my pool is at the upper end of the Frog recommendation on 1ppm. What should I run the pool at for chlorine levels?

You should follow the FC/CYA Chart.

The frog dumps silver in to your pool to prevent algae. This, however, does absolutely nothing to sanitize your water. Running 1 ppm FC with 50 CYA (round up) is potentially unsanitary. Algae might be unpleasant to look at, but bacteria that you bring in to the water is invisible and actually dangerous. The kill rates at that low FC are not especially reassuring.

Not to mention the Frog is horribly overpriced and a completely proprietary system forcing you to purchase replacements from the pool company. Of course they really like it, it's a cash cow! One came with my house and I used it for a couple of years. One major algae bloom led me to TFP. That led me to recognizing just how little I wanted that copper and silver (so-called "minerals" ) in my water and I removed it permanently. Since following TFPC my water has never been easier to maintain, clearer, or more comfortable. Not to mention at a much better price.

Done - I will turn the frog to zero in the morning and feed the pool a bunch of bleach. I also didn’t realize that the bac pacs add CYA. That could get messy fast!

One more question while I have the experts here. As a pool newbie I put in non-Chlorine shock this weekend and after reading up on the topic more and more on this site, that appears to be a no-no. How long will my DPD tests be skewed for? Do I need to buy the Taylor kit or will the MPS go away over time and I don't need to worry about it if I don't add any more?

The MPS will dissipate over time. It primarily effects the CC reading. So I would not be surprised if that would be elevated for some time.
