    Back again with numbers.....

    I got my pH up to where it belongs and I went to the pool store to get a free water test:

    FC .93
    pH 7.1
    Hardness 5
    TA 18
    CYA 20

    They want me to add 50lbs of calcium. Apparently it can cloud the water and not very fun to pre dissolve.....????? The "school" says to sprinkle it in the deep end????

    They also want me to add stabilizer. I think that it is ok

    I did however add baking soda.
    Thanks a bunch....!!

    You have a vinyl pool and don't need CH at all, too much can cause scaling though and the only way to remove it is to replace water. I wouldn't trust the pool store testing, especially the CYA. If it's right you could use more CYA but again the only way to remove it is to replace water. You ought to get one of the recommend test kits in pool school and test your own water.

    You don't need Calcium in a vinyl pool. Buying hardness increaser is just money wasted. Spend that money on something useful - your own test kit!

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!

    2. Add enough CYA in your pool to get to 60 ppm.

    3. Add enough liquid chlorine into your pool to get to about 4-6ppm and then keep it there until you bring your SWG online.

    read "The ABC's of Pool Water Chemistry" up in Pool School. Then, adjust your chemistry one parameter at a time. dichlor seems counterproductive in a pool with pH too low.
