The formula you’ll use to measure your pool will differ based on the shape of your pool. For a rectangular pool, you’ll use the following formula to find the size in gallons: length x width x depth x 7.5. If the depth changes from one end of your pool to the other, take the average by finding the depth at the deepest and most shallow points and dividing that number by two. Circular and oval pools require different, more complicated formulas, which can be found in this article.

There are some disadvantages to a salt water pool. Besides costing slightly more than chlorine pools, salt water pools require a lot of salt. It's also harder to find a professional with salt water pool experience to do minor maintenance and repairs. Salt water can also damage some materials, so you’ll need to use specific heating, fixtures, lighting, liners, and masonry when building a salt water pool.

The time it takes for a pool heater to heat a pool can range from eight to 48 hours, with an average of about 12 hours for the initial heating. For a more specific example, an average-sized 15,000-gallon pool may take six to 10 hours to heat up by 10 degrees. The exact duration depends on several factors, including the pool's size, the type and size of the heater, the starting water temperature, and the outside air temperature. It may take some trial and error to determine the precise time your specific pool takes to reach a desired temperature.

Most of the time, though there may be some code variations on the local level, a water source like a pool requires a GFCI breaker. These breakers detect electrical leaks of 5 mA or more and trip the breaker. However, the size of the pool and motor type determine the exact GFCI needs. A GFCI outlet with a reset button may be enough for an aboveground pool with a small motor or pump. Consult a pool electrician to determine the appropriate installation and protection measures needed for your pool.
