    Opinions on test results

    Hi everyone! I haven't posted here in several years, but I lurk off and on during pool season. Yesterday my daughter shocked our pool using leftover powder shock that she found in the garage rather than the bleach that I had sitting on the shelf Anyway, today after vacuuming the pool the water looked a little cloudy, so I ran some tests using my TF-100 kit.

    CYA 20
    FC 10
    CL .5
    Ph 7.2
    Alk 100

    From what I can tell, the FC is at shock level based on the CYA reading. The pool is still a bit cloudy, but not very much. Just not the crystal clear water it usually is. I'm not sure what my next step is to get it back to sparkling.

    Continue to maintain the shock level until you pass the 3 criteria to stop the ShockLevelAndMAINTAIN Process, one of which is the water is clear.

    Why did she add the powder? There should never need to be a reason to "shock" if you maintain adequate FC levels.

    When you get cleared up, you should raise the CYA to at least 30ppm.

    What kind of powder was it? Cal-hypo can cloud the water, although usually only when the pH is also high I think.

    She used TurboShock trying to help. I tested the pool the day before and couldn't get a FC reading so I mentioned that I was going to shock the pool. So she was trying to help me out by doing it (she is probably planning on inviting friends over to swim this weekend)

    Do you understand the SLAM process and is that what you are going to do? If you start ASAP, you might be done by the weekend.

    Turboshock is Cal-hypo and that can cause cloudiness.

    You may very well be at shock level, but to clear up your pool you need to get it to Shock Level And Maintain. Follow the instructions carefully and don't neglect to brush and clean the ladder and/or steps.

    If the cloudiness isn't algae, you might just have the briefest SLAM to date.

    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!
