Salt Water Pools: How much salt do I add to my pool? Do I need a Zinc Anode?

Salt Water Pool:

How much salt do I need to add?

You only need to add salt to your pool or spa if your chlorinator control box indicates your levels are low or, obviously, you have completely (or significantly) drained your pool.

The salt level for a safe, chlorinated pool is about 2, 500 to 4, 000 PPM (parts per million). Most people can’t taste salt until the PPM is around 5, 000. So for most people, it’s not even noticeable.

Here is how to figure out how much salt you would need after just filling it with fresh water.

If you don’t already know, estimate how many gallons your pool holds.

The formula (using feet) is:

Average Depth x Length x Width x 7.5 = Gallons

The average depth = (depth at shallow end + depth at deep end) divided by 2

Example:

The pool is 50’ long and 20’ wide. The shallow end is 3’ and the deep end is 9’.
Average depth = (3’ + 9’) / 2 = 6’
6’ x 50’ x 20’ x 7.5 = 45, 000 gallons

If this is a new pool, you will need 50 lbs salt for every 2, 000 gallons to get about 4, 000 ppm, a good starting point. So for this example, you would need 1, 125 lbs of salt

For existing pools, the previous usage of chlorine bleach or tablets will have already created a level of salt in the water. Have the water tested and then add the appropriate amount to establish 4, 000 ppm.

Just recently, I've noticed the emergence of salt water pools. There was one at the hotel (nothing fancy) where we stayed in Lincoln City. Also, the Courthouse Athletic club in Salem has one.
I think it would be best to call around to your local pools and ask where the closest salt water pool is. There must be something in Portland!
Good luck!
