If a pool turns green after adding salt, there’s a good chance the salt is the problem. Certain brands of salt have high levels of iron that cause pool water to take on a green hue. Test your pool water to determine if this is the issue. The green color will usually filter out. Brush the sides of the pool to knock the iron off.

This is just one reason a pool can turn green that is specific to adding salt. Many other reasons a pool can turn green include algae growth, low chlorine levels, a faulty filter, etc.

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.

No, you shouldn’t be able to taste the salt at all since saltwater pools only contain about 10% of the salt you’d find in ocean water. Saltwater pools do create some chlorine, though, so you should still try not to drink the water.

Because they are smaller than an average-sized swimming pool, building a plunge pool is less costly than a traditional pool. In-ground swimming pools cost about $67,000, while plunge pools cost around $20,000. You won’t have as much room to swim in, but the smaller size means you spend less on land excavation, materials, and hourly labor rates.
