Pool Boy Pro Features Unlimited poolsUnlimited alerts per swimming poolUnlimited equipment per poolSynching Between Devices No ads are displayed Download Pool Boy Pro from the Apple App Store You can set up alerts for simple tasks such as adding chlorine, cleaning baskets, cleaning the filters, topping off the water, or some less frequent such as replacing the sand in the filter or whichever you desire since all alerts are fully customizable by day interval between alerts, time, and alert name.Pool Boy also has a nifty water parameter log which includes fields for pH, Chlorine, Alkalinity, Total Dissolved Solids, Calcium, and Cyanuric Acid. You can then graph each test over a week, month, 6 months, or 1 year individually.Pool Boy's calculators are adjustable to fit your maintenance products needs. Chlorine shows the level of disinfecting chlorine available to keep your pool sanitary. pH indicates how acidic or basic the water is. Total alkalinity indicates the water's ability to buffer pH changes. Buffering means you need to use a larger quantity of a chemical to change the pH. Over time, water with low calcium levels will tend to dissolve calcium out of plaster, pebble, tile, stone, concrete, and to some extent fiberglass surfaces. Cyanuric acid, often called stabilizer or sometimes conditioner, both protects Chlorine from sunlight and lowers the effective strength of the Chlorine. The level of Total Dissolved Solids in the pool is influenced by the chemicals we add, dust, dirt, human waste, and objects which fall into the pool. Salinity is for those who have salt water pools to be able to log the amount of salt in the water.
