To determine how much salt to add to an 18x4 pool, you first need to know the pool's volume in gallons. An 18-foot diameter pool that is 4 feet deep has a volume of approximately 6,600 gallons. For a saltwater pool, a typical salinity level is around 3,000 to 3,500 parts per million (ppm), which usually requires about 40-50 pounds of salt per 1,000 gallons of water. Therefore, you would need approximately 260-330 pounds of salt for your pool.

How much salt needed for new pool?

The store where you bought the salt system can probably tell you how much. It all depends on how big, and thus how much water is in your pool. If you tell them the size and depth of the pool they should be able to tell you about how much salt you'll need to add.

We have no free chlorine in the pool how much salt do you need to add?

That depends on the size of your pool and the level of salt your chlorine generator needs to properly function (usually 3200-3400ppm). If you do not have a quality salt test, I recommend bringing a sample of your water to a local pool store to be tested. Bring your chlorine generator's manual with you and they will help you find where it shows how much salt to add. If your pool has been low on chlorine for more than a day or two, or if the water is cloudy or green, you will need to add some liquid chlorine to assist the chlorine generator in clearing it up.


What mean salt?

If you have a salt-water pool and you have an indicator that says add salt it means that the amount of salt in the pool is not enough for the chlorinator to manufacture chlorine. Take a sample of water to your pool shop and they will help you with what is required. Or get a couple of bags of salt and add salt until the salt warning stops. The latter is a bit of a dodgy way of going about it.

How much salt goes into a swimming pool?

It depends how many gallons your pool is. Once you buy your chlorinating system, the install manual will tell you how much salt to add based on how many gallons in the pool. I have an Autopilot Digital and it tells me when it needs salt. I still check it with test strips to be safe.
