well filling new pool. treat to prevent?

[induce]

The liner is going in our new inground pool. we have to fill it with well water (only thing available). I had it tested for metals at a local dealer and was told it contained below normal levels of metals......... good news, but i'm a bit of a skeptic.
It is a salt system, but pb wants to run on chlorine for 2 weeks before he fires up the salt system.
I'm thinking of adding jack's or metal magic as a stain preventive. I've heard of Proteam's product causing a very bad preciptate and cloudy water that only draining would solve.
Any insight would be appreciated!!

A dealer will typically do what it takes to sell you something. If they aren't trying to sell anything, you are probably fine. Don't get in the trap of adding things because it sounds like a good idea. There are downsides to everything you put in the pool.

My suggestion would be to watch the pool as you add chlorine. Add the chlorine slowly, keeping your ph on the low side - about 7.1 to 7.3. If you see any discoloration starting you can add a sequestering agent. Jack's Magic is good, and so is Metal Free. If you use the sequestering agent when you first see staining, and have your ph at 7.0 to 7.2, it will lift the stains off. I have well water, and my water does not test high for metals, but I do get staining. I have a fiberglass pool which is more suseptable to stains than vinyl. It is up to you whether you want to put the sequesterant in first - but I would wait because stains are not hard to get rid of, and you will be saving a lot of money if you don't need it.

thanks for the tip Marie............but i already jumped.
Used 2 bottles Jack's purple stuff after much research.
filled pool last sat. pumps on line monday. water looked pretty bad sat. today (wed) super. very clear, fountain on to lower the TA. (started @ 450+) now :
pH 7.6
Cl 0
CYA 20
TA 350
Ch 250

doing the acid/areate, raising CYA, Adding bleach, adding acid, poly 60 in, running pump on high 24/7....water 90 degrees.......love the heat pump!!!

Sounds great! Just remember to add the bleach slowly, raising the level by 1ppm at a time, since your water is so clear you don't need to shock. With the temp at 90 (you lucky guy) I would get some chlorine in there. I would also add some acid to get your ph down to 7.0 before you add the bleach - you won't get your alkalinity any lower if you have a ph at 7.6, it has to be low to out gas the alkalinity. The ph will raise as the alkalinity lowers, so you have to keep adding acid to bring the ph down to keep the cycle going. Enjoy the pool!

Marie,
why add the chlorine slowly? i'm having trouble maintaining cl levels. today 0, with a bit of CC. total of 6-8 gal bleach since sunday.
CYA is up to 40 today, so i am stopping the CYA. want to add more cl tonight. Why not shock to raise levels and get rid of CC. I was thinking 7 -10 ppm..............bad idea?
TA down to 300. pH back to 7.6 after being @7.1 this am.
