We will be ready to turn on the new salt cell in two weeks. Being that this will be our first salt and looks like we will need a lot of salt to get this going any recommendations for a large bulk order? Or ones to stay away from?
 
Stay away from Clorox pool salt.

Mortons pool salt and Diamond Crystal pool salt are good.

If this is not fresh new water then check your salt level with the K-1766 Taylor Salt Test before you add any salt. You may have more salt in your water then you expect.


Salt can be added using solar salt, sold for use in water softeners (sodium chloride). You want the kind that is 99.4% pure or better and which doesn't have any rust inhibitor or other additives. Crystals are fine. Pellets will work but dissolve slightly more slowly.

The purer the salt, the better the life and performance of the Chlorine Generator. Use salt that is at least 99.8% pure NaCl, sodium chloride. The preferred and recommended salt is an evaporated, granulated, food quality, non-iodized salt with no additives.
  • Avoid using salt with anti-caking agents (sodium ferrocyanide, also known as YPS or yellow prussiate of soda). Filling agents can cause some discoloration of fittings and surface finishes in pool.
  • Water conditioning salt pellets are compressed forms of evaporated salt and may be used, but will take longer to dissolve. Such pellets could damage pool plaster and other surfaces in and around the pool.
  • Do not use calcium chloride or potassium chloride as a source of salt. (Use sodium chloride only).
  • Do not use Rock salt (insoluble impurities mixed with the rock salt can shorten the life of the Cell)
Pool store salt generally costs more and is more finely ground, but even pellets dissolve quickly enough so that isn't really any advantage. Be aware that salt is a naturally mined or harvested (from slat flats) product.

The type of salt sold for pools is not a highly pure chemical grade of salt and therefore will have some impurities in it form the mining process.

If you are doing an SWG pool startup process, then you could be adding hundreds of pounds of salt to your pool. Even if your salt is 99.5% pure, then every 100 lbs of salt added will add 1/2 pound of “impurities”. This can often lead to cloudy water that will take time for your filter to remove. Most of these impurities are just silica dust or other non-toxic compounds.

Clorox Pool Salt has been reported by multiple members to stain pools.
 
Thanks for the detailed info. Pool was just filled after the remodel couple weeks ago. We had planned to move to salt as part of the remodel and have everything ready to go......other than all the salt for about 30K gallons
 
As your SWCG will not be generating until your water is above 55F or so, you might want to delay adding the salt until the water temperature is at the level needed by your SWCG to operate.

So based upon that which had slipped my mind about the temps. Would be better to wait till spring to add salt and just run tabs for the winter?
 
We had a member in the spring that gained 600ppm salt from the startup chemicals after a refinish while waiting the 30 days. Whenever the time comes, test first so you don’t overshoot. (y)

Up to you if you’d rather add soon or wait. It’s half a dozen or six.

You need to use tablets or liquid chlorine for the winter whether you add salt or not.

Where will you be putting the tablets? You have a floater?

Nope will need to pick up a floater.....our old pool service always just placed them in skimmer baskets which seemed odd to me.

Yup, you need to use a floater.

Putting tabs in the skimmer is more then odd. The acidic water it creates when the pump is off can damage equipment.

Each 8 oz trichlor tablet will add 1.8ppm of FC, 1.1ppm of CYA, raise salt by 1.5ppm and lower pH by 0.1. Watch your CYA and switch to liquid chlorine if your CYA is approaching 70.
