    New Home Owner-huge in ground pool

    Ok please, I need some help! We bought our home last October. My husband came and closed the pool with the previous owners. We decided to start opening it a few weeks ago. When we pulled the cover off it was very green. We went to our local pool company, told them we have 50,000 gal pool and they told us how much shock to add. We came home and added shock, and it didnt get any better. We are constantly running the filter (sand filter) and backwashing. My husband added more shock, still nothing. We then took a water sample to the pool company and they tested it. At this point, our liner had now turned a nice shade of orange and the pool still green/brown. Upon testing the water they said that we had iron in the water. We had to treat it with "Chem-Out" 1st and then "bear-magnet" to lift the stains off. My husband followed their instructions to a T and no change. We went back with another sample, the iron was no longer in the water but our Chlorine level was off the charts (hot pink on the test kit). So they sent us off with the same treatment (though free this time) and told us to put in the "Chem out" wait 24 hrs and test the chlorine. We did, and still PINK! Went again to pool company. Now we get sent home with 12lbs of "Bear Blast", told again to test the chlorine in 24 hours. Once again we did and no change. Today we called and then went again, now they have us adding 12lbs of Nuetralizer. Basically they are telling us before we can remove the stains and get where we need o be, we have to get the chlorine out. I am very discouraged and dont know what to do. I think the size of the pool is 25x40, its huge and holds approx. 50,000 gallons of water. Right now it looks like we have Shrek living in our back yard. Can anyone help us??

    Welcome to tfp, KSMITH76

    Going to the pool store and following their advice of tossing stuff in is obviously not helping you. You need to get control of your pool, and the first step is to get an appropriate test kit. See:

    As you wait for you kit, then read read read pool school (link is always near the upper right of the page). Here is a great starting point:
    TFP Expert who uses Pool School and my TF100 test kit along with PoolMath for my: Round 11K gallon AGP with deep end, 20" sand filter, Matrix 1hp 2spd, 6 2ftX20ft solar panels (and solar cover!), Intex SWCG (copper bars disconnected) and a Rubadub hot tub (chlorine). The SLAM process is not finished until: 1. CC < 0.5 ppm, 2. An OCLT < 1.0 ppm and, 3. The water is crystal clear.

    Might want to double-check that volume estimate.
    Mine is 55,000 gallons (after a good bit of debate), and it is 75'x20-25'. Yours would be a bit less than that.
    25'x40' with average depth of 5.5' is around 40,000 gallons.
    One way to sort-of check this is to get a good test kit, and use
    Then you will see what happens when you add a known amount of chemicals to a pool with a specific volume, and you can test yours to see if it matches up.
    If not, then adjust the volume estimate until it matches reality, then you have a pretty good idea of the true volume.
