## Adjusting pH Down after raising Alkalinity
Gemini says this should be done with a Matrix or Dynamic Algorithm, and the Algorithm sounds like the best option. However, instead of a "dynamic algorithm" like Gemini probably intended, I think several formulas might work fine.
Simply put, we first check the input Total Alkalinity (as provided by ALEX), and see whether it's above, below, or inside the target range. If the input is below, we would run the formula to determine how much Alk. Increaser is needed to reach the target range, preferably as close to the middle as possible, and "log" that number, which is our new TA.
Next, we need to figure out how to adjust for pH. We start with a simple formula:
Base Dose (fl oz) = [Pool Gallons / 10,000] * ([Current pH - Target pH]/ 0.2) * 10
`Base Dose (fl oz) = [Pool Gallons / 10,000] * ([Current pH - Target pH]/ 0.2) * 10`

Adjusted Alkalinity is the Total Alkalinity minus the CYA multiplied by Correction Factor, which is based on the pH.
However, since pools are usually between 7.2 and 8.2 pH, just use the following to get Adjusted Alkalinity:
AA = TA - (CYA * 0.33)
`AA = TA - (CYA * 0.33)`
Basically, keep TA at around 80-120 during the winter, and 60-90 during the season
