Still not enough salt?

[Kemble]

Filled a brand new pool last week. 11,000 gallons

I put 6 (40lb) bags into the pool yesterday and the SWG still reading red light (not enough/low salt) I as told tat I should have salt in the water that I filled it with and 6 bags should be plenty.

I do have the TF-100 test kit so I can check the content. But I just was wondering on average, how many bags does it typically take for a fresh fill?

K,

You can use Pool Math (Link the top of this page) to figure that out.

Enter your pool size at the top and then go all the way to the bottom and look for "effects of adding chemicals"

If you enter 240 lbs of salt you will see that brings you up to 2600 ppm. The IC-40 needs a salt level between 2800 and 4500 to operate correctly..

Try Pool Math yourself and see what you get..

Thanks for posting,

Jim R.

Kemble, I have a 10,000 gal pool. Since start-up this April I put in 8 bags of 40 lbs to get to 3400ppm which the IC40 likes to work with. Maybe I lost some to slight draining from to much rain, but you will need at least that.

Thank you guys. I just was getting scared adding in so much salt, I didn't want to overdo it. I throw 2 more bags in it this afternoon.

BTW... How often will I need to replenish the salt once I get to the 3K range ? I bought my 1st to bags from the pool store for $19.95/bag. Then I went to Walmart and saw the SAME SALT for $3.00 per bag. Boy was I @*$$#!...

Anyhow, how many bags should I buy to keep in reserves in my shed?

I would not buy any extra. You might need to add one or two bags every year at opening. It just depends on the amount of Splash out and overflow you get from rain and if you have to backwash a lot.

ok so the SWG doesn't "consume" the salt when making chlorine? or it does, just not fast enough to worry about it until next year and just add some at opening.

No, it consumes water.

In simplified terms

H₂o + NaCl + electricity = NaOCl +H₂
Water + salt + electricity = Sodium Hypochlorite bleach + Hydrogen gas. Those are the bubbles you see inside the chamber. Then the Bleach degrades into Salt again as it oxidizes organic material.
