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.

Generally, you do not need to drain your pool to convert it to a saltwater system. The main exception is if you have used an antibacterial agent containing polyhexamethylene biguanide to sanitize your pool, as these sanitation products do not mix well with saltwater systems. If this is the case, you will need to start fresh. You can either drain the pool or treat the existing water with a high dose of chlorine to remove the antibacterial agent. If you choose the chlorine treatment, wait several days to allow the chlorine to work before proceeding with the conversion. If you are unsure whether this applies to your pool, consult a pool technician.

Pool maintenance costs an average of $230 per service, with prices ranging from $50 to $750 per service, depending on several factors. The type of service will usually be the most significant cost factor, as opening and closing a pool takes a few hours and can total $400 or more, while regular cleanings could cost under $100. The size of your pool and the type of pool—above-ground, in-ground, saltwater—can also affect the price of maintenance.

Concrete pools have the longest life span. As long as you properly maintain your concrete pool, you can expect it to last 50 to 100 years. That said, you will need to resurface your concrete pool as it ages. Fiberglass is durable, but fiberglass pools generally only last around 25 to 30 years. That said, some high-end fiberglass pools can last more than 50 years if they’re well-maintained.
