Poolside Chat Episode #35: Lowering Swimming Pool Salt Levels

• How many gallons do I drain from my pool to correct its salt level?

Now here’s your hosts – Matt and Rob.

“How much water needs to be replaced in order to lower the salt reading to an ideal level?”

You may be wondering why a high salt level is bad for the salt chlorinator. The reason being, is if the salinity level is too high, the chlorinator will stop making chlorine and that’s no bueno.

We have a simple math solution that’ll tell you how much water you need to drop from the pool.

Let’s say your current salt level is 4500 parts per million and your ideal level is 3200 parts per million. You’ll subtract the 3200 from the 4500 which gives you 1300 parts per million. That’s what you need to drop. You divide 1300 by 4500 and that gives you .28888888. For this, we’ll just round it up to an even 29%.  You need to drop roughly 29% of pool water.

But if you’re trying to figure out how many gallons are in your pool–let’s say our pool is 10,000 gallons you’re going to multiply that by 29% which is .29 and then that equals 2900 gallon. Now, you’re going to take that water out which is about 1/3 of your pool and then you’re going to add fresh water and then everything should balance out at the end of it.
