First Time Testing - Salt Question

[JeremyKC]

So I opened up the pool about 6 weeks ago and it has been crystal clear. We haven't been swimming due to the weather, but I decided today that I would become familiar with the TF-100 test kit.

Here are my numbers:
pH 7.8
TA 100
FC 15
CC 1
CH 200
CYA full to top and it finally disappeared
Salt 6400

I tested the salt 3 times and keep getting 6400 ppm. When I opened the pool, the guy at my pool store asked me if we switched from salt. I said no, why? He said you have 0 salt at all. I thought it was strange but they have never steered me wrong. He sent me home with 20 bags of salt. I should have questioned it because we only normally add 8-12 ever.
So if I am testing this correctly, I have twice the amount of salt I need, so I need to dump half of my pool water and refill.
Does this seem right? I don't think I can be doing the test wrong and get the same result 3 times right?

Not likely. I suspect you need to drain 50% of your pool water and replace with fresh.

I would take a sample back to that person and ask them why they told you to purchase and add unnecessary salt. At a minimum get a refund for the salt plus some free CYA you will need.

Sounds to me like you've been Pool-stored.

A partial drain is in your future. At least you hadn't raised CYA yet and have to waste that, too.

Reduce the salt to something your SWG will be happy with, let the water mix, retest, and try again.
