    Question Getting started for the second time

    Hi Everyone,
    It has been many years since I was here last. Sorry but all was going great after learning how to maintain my pool here. THX.

    My return/revisit today is that I plan on draining 50% of my pool after 7 years. The reason is because my chlorine is being eaten up and my CYA has gotten lower and the test show I have contamination from rain and other issues that I won't get into but some wrong chemicals added while I was gone by my daughter. So instead of playing games I decided to reduce my water level by 50% and refill with fresh water.

    The pool opened February 2008.
    During this time everything worked well.
    SWG cleaned every 6 months
    Cleaned filters 3 or 4 times a year
    Water has been basically well balanced chemically until the last 3 months.
    My PH is perfect as well as all others but my chlorine is being eaten up very quickly.
    Water super clear, No algae.
    Yes I still need to refill 50%.

    Normally these are my readings.
    FC levels 1-3 ppm
    PH 7.2 to 7.6
    TA 110 - 130
    CYA 80-100
    CA 250
    Salt level 3200 ( Goldline limits 2700 -3400)

    PLAN IS................
    Start draining pool down about 50% which is about 5,000 to 6,000 gallons.
    As I'm draining I plan to acid washing the tiles at water level to remove 8 years of calcium build up.

    1. After filling back to level I will install four new filters.
    2. Next I will start adding CYA over a few days and test regularly to insure good reading.
    3. I will add initial liquid chlorine but haven't decided bleach or pool store stuff. After that the SWG will take over.
    4. Will add approx. 100 lbs of salt as I figure my salt level will be divided in half down to 1,500 and to get back to 3,000 the chart says just over 100 lbs.
    4. I will run pump on a regular schedule and test, test , test.

    My questions now are...

    1. Does this plan sound reasonable with the proper order I need to do this or does it need modifications?
    2. Can I use liquid bleach or just use liquid chlorine from the pool store before switch back to my SWG?


    Thanks in advance and hope to hear from you all soon.
    I will also post how things are going but I have to wait another week to insure the rain stops here in the Arizona desert.

    If you refill, you will need to keep your minimum FC level between 4 and 6, as recommended here:

    Can you post a current set of test results? You may not need to drain if your CYA is within normal SWG range, a SLAM may be a better course of action.

    What size is your SWG, what % do you run it, how many hours day and how old is it?

    You can use liquid bleach or liquid chlorine, there is no difference other than concentration.

    Your normal FC is too low. 3 should be the absolute bottom, I recommend shooting for 5 or 6 to ensure you never fall below 3.

    UPDATE
    After a few more test of the water and testing SWG here is the answer I was looking for.

    FAC - 0
    TAC - 0
    Salt - 3500
    Calcium - 280
    CYA - 100
    TA - 100
    pH - 7.7
    Copper - 0
    Iron - 0
    Phosphates- <100

    Tested Installed SWG T-15 Cell - Failed
    Tested Original backup SWG T-15 - passed.

    Solution installed original good SWG cell
    Added some shock to help working cell to catch up.
    Set cell timer to 50% for 8 hours a day.

    We will test over the next week after the rain and plan to lower pool to reduce CYA as it is over 100% now.

    Sorry for jumping to conclusion that it was a water chemical imbalance and it just happened to be aa bad SWG that has been running all summer.

    Will write a follow-up in a few weeks.

    I'm happen now.
    Thanks all.
