Thread: Well water pre fill test

  1. Back To Top    #1

    Well water pre fill test

    My pool will not go in for another few weeks but I just got my tf100 and I wanted to see where things were at. Here are my numbers:

    This is well water and was probably at about 55 degrees.

    ph 7.2
    ta 370 to 450 (at 370 I saw the first glimmer of red- it increased with every drop and was pretty red by drop 45)
    CH 320

    I didn't think the other tests applied just yet.

    I have been reading and it seems I can manage my TA with an aerator and my CH might not be unmanageable. I will also have a SWG (that's helpful for CH right?).

    Do these seem like manageable numbers? Should I take a sample to a pool store to test for metals etc or does the TF100 have me covered? Please tell me I don't have to pay to have water trucked in.

    Thanks in advance

    Just trying to get a bit of a handle on this before the real test begins.

    Re: Well water pre fill test

    They are not horrible.
    You can lower the TA with some work (acid and aeration).
    Some members have CH a LOT higher than that.
    SWG has nothing to do with CH ... you will need salt not calcium.
    Might be worth having the pool store test the water ... do a full test including metals ... don't tell them it is just well water and lets all maybe have a laugh at the results

    I just re-ran the tests on water that was run through my whole house filter and softener (just for giggles).

    Thanks. So the pool store can test for everything I would need to worry about? I thought I read some posts about people sending their water to the state testing facility or something. I also thought I read somewhere that a SWG helps with the effects of CH- like bonding or something.

    Re: Well water pre fill test

    Almost makes you wonder about the point of the water softener.

    I think there are state required testing for wells in many areas, but you are just trying to find out how much iron/copper/etc might be in the water. Who knows how accurate the pool store will really be though.

    Re: Well water pre fill test

    Thanks Jason. I guess I don't have many options. I'll take them a sample and post their results.

    Re: Well water pre fill test

    Just got back from the pool store. Here is what the kid who was on the phone the entire 20 minutes I was there wrote on the sticky note (verbatim).

    ph 7.8
    alk 120 (TA?)
    hard 300 (CH?)
    copper .30
    iron 2.80

    I reran my numbers when I got home just for fun.

    ph 7.3
    ta 370
    ch 260 (I adjusted this test since I now know there is copper in the water)

    What does it all mean?

    Re: Well water pre fill test

    Pretty big difference in the TA / alk numbers.

    I am not sure at what levels metals are an issue. Here is some reading to get you started from Pool School:

    Re: Well water pre fill test

    You may want to take a sample to a second or third store for confirmation on the iron / copper numbers

    Re: Well water pre fill test

    I might have to get another test. There is another pool store pretty close.

    Linen mentioned in my aquipment thread that I may have to use sequestrant- it looks like he was right.

    Re: Well water pre fill test

    Pool store number 2 just did copper and iron.

    Copper .34
    Iron 2.5

    She said the copper number was negligible and I can handle the iron number by adding sequestrant as I fill. She said wait for a few days before adding chlorine.

    I should have had her test the alkalinity too I guess, but at least I can do that at home.
