High salt levels after treating for algae

[Mcaveman]

James all my levels were good before the algae , salt was right around 3500

What SWCG do you have? Please add it to your signature.

It’s a pentair IC-60 i will add to signature

Not sure why it’s not showing my signature.

I see nothing on the label about not using in a salt pool .

That's because they just want to sell their products.

Does the K-1766 salt test kit agree with the Easytouch?

 

[JamesW]

3,500 ppm to 4,800 ppm is a big jump.

Either salt was added or the readings are wrong at some point.

 

[Mcaveman]

Yes it does . ~4800

 

[Mcaveman]

No salt added just bleach and the algicide (sodium bromide)

Your signature is showing. If on a mobile device, turn the device sideways to see signatures.

1,300 ppm - 366 ppm = 934 ppm.

934 ppm is 352 lbs of salt or (8.8) 40 lb bags.

Would the bromide raise it that much ?
google results say the sun will burn the bromide up , is that true ?

 

[JamesW]

The sodium bromide will raise the salinity by about 10 ppm.

Bromide does not burn off.

It should diminish over time, but there is no easy way to tell how much is in the water.

You're stuck with it for a while.

The sodium bromide would have raised your salt level by about 15 ppm. Also it isn't an algaecide, it does nothing to kill or prevent algae by itself and should never be added to a chlorine pool.

The sun doesn't burn bromide up, it burns up bromine. See, when you add chlorine to a pool with a bromide bank (like yours) it reacts with the bromide to create bromine. That bromine then either reacts with something or gets burnt off by the sun. It then reverts back to bromide, which will react with chlorine the first chance it gets to repeat the cycle. So during the day the sun is just burning away bromine, which then gets replenished by any chlorine there might be in the water.

Bromide is basically forever, it will take a 100% water change to get rid of it.

First off thanks for all the replies so fast, its safe to swim if the water is clear ? What FC levels should I shoot for ? I would like to wait until start of next season if I have to replace water, some conflicting information about if its forever or will go away.
