    Can you make sure I'm doing this right?!


    Can you read over this and make sure that I'm doing this right? I'm still a newb and making sure I take baby steps.

    I have some algae, not much but enough.

    Test results:

    FC: .43
    TC: .48
    pH: 8.08
    TA: 130
    CYA: 51
    Salt: 2500

    Pool info: IG/SWG/DE filter/15000g The water is very clear I can see the bottom...the algae is mostly on the bottom and sides of the pool.

    I checked the pool filter and pressure, they're fine. I know I need to reduce my pH to the 7.2 range before shocking. I know I need to turn off my SWG filter and run the filter 24/7. Here's where I need clarification, when I put my CYA #s into the pool calculator it states that I need to bring the shock level up to 17(add 445 oz of bleach).
    Is that right?

    Am I missing anything?

    Thanks in advance for any and all assistance!

    sounds right, test after adding the chlorine just to double check.

    You are correct, on all counts. Get that pH down and then hit it with the bleach! about 4 gallons to start!

    "Shock" is a process, not a product!
