We base our models on typical residential, full size, pools. So unless your pool is unusually large, or you have many more swimmers in it than most people, you should have enough chemicals.
There are a number of other factors that impact chemical usage as well, including water evaporation due to hot weather. We can't confirm right now whether this is enough to make you accrue any extra charges during the summer months until pHin gets in your pool and learns about it. If pHin determines that your pool will need extra chemicals, we’ll contact you to discuss options.
There are ways to decrease the rate of evaporation, including using a cover, or adding a liquid that acts as a cover for your pool.
