    Hard well water

    We used well water to fill the pool, CH is way higher than 300. Straight out of the faucet it's 550. Testing in the pool I'm about 700. Intex ultra frame with SWG. Replacing the water obviously won't be any help. Does it matter I'm so high above 300?

    Standard cartridge filter and SWG that came with the pool
    I started off with a Taylor test kit, but my refills are coming from TFT so I am not sure what kit you would say I have.

    What will help is to keep the pH around 7.2 and the TA between 70-90ppm. You can manage water with high CH if you keep pH on the low end of the recommended levels. High pH may lead to scale formation.

    kne,

    You will be able to deal with the high CH by taking zea3's advice.

    Please have your well tested for iron......that's where you will have a hard time.

    Do you have rust around the toileyts, sink's etc? Do you have a whole house water softener?

    The CH (at those levels you report) is manageable........crossing my fingers you don't have to deal with iron which is much more difficult.

    Re: Hard well water

    Thanks guys Inside the house we are on city water, we use the well for everything outside so no toilets to check out. Is this a pool store test?

    Yes, the Iron test is done at the pool store. You could buy your own, but it's awful pricey just to test once.

    I would kind of doubt you'll have Iron, since there's not a history of Iron mining in the East Bay. If the native soil is reddish, you're probably okay.

    Re: Hard well water

    I live close to a Leslie's so I'll get it checked just to know. It'll be fun to compare their numbers to mine I'll work on keeping the PH & TA on the lower end as suggested. If I remember right, last year I used a lot muriatic acid to keep it in check.

    I hate when I hear that. Their lack of reliability is seldom fun. Trust your own test results...Always!

    Awe duraleigh I know my tests results are spot on! But since I've never had my water tested by a pool store before and reading all the horror stories on this site, the analyst in me can't wait to see the difference
