Freezing point of salt water pool, is it slightly lower?

[brucehenson]

If a salt water pool has a slightly lower freeze point (?) should you add salt even though your SWCG is not functioning?

 

[mknauss]

The change in freeze point is imperceptible.

No need to maintain salinity in the water until your SWCG is able to generate chlorine.

I believe the Ocean freezes at 28 Degrees and it has 10x the salinity of a salt water pool...any difference in the freezing temperature probably wouldn't even be measurable in your pool.

Thats what I thought, thanks for the responses.

Curious why do you put salt on ice to make it melt? Thinking folks icing the roads and also ice cream salt?

I know the road part. Salt directly on snow or ice won’t do anything on its own. It needs the sun or friction from vehicles driving to warm the roadway first. Once it does, the salt mixes with the melting ice/snow and creates a slurry that won’t easily refreeze. To speed this process up, many places use a salt spray.

The Physics of Freezing and Freeze Protection

Recently, there have been a lot of questions from those living in moderate climates about using automatic freeze protection or running pumps to prevent freezing and what a pool owner should do when temperatures drop so I thought it might be useful to have a thread which dealt with the issue from...

I am in Atlanta so not a huge concern here but never know..I know a few years back my pool froze a couple inch's and a couple friends with SWG said theirs was a just thick slush but they did keep the pump running.
I did read on the internet salt water freezes closer to 28 then 32 and because it's on the internet has to be true

I drain mine down between the tile and jets usually, again we our cold snaps come at night and usually warm up during the day. But like they say in Atlanta, if you don't like the weather, wait a week it will change

And sometimes only a day in lots of places.

in melbourne, australia, they say "if you dont like the weather, wait a few hours"

I thought it was only because something would crawl out of the ground and kill you.

This thread has clearly run it's course, but I'm sure I've heard people from about every state same the same thing. It's quite comical when you pay attention.
