    AG Pool Opening

    Hi,
    We've been using the BBB method a few years now , but we always seem to need some help at opening. First, our pool was a mess when we closed it and surprise, surprise, it was a bigger mess when we opened it on Sunday with lots of leaves and a very dirty bottom. We raised the water level back up, raked out as much of the debris as possible and vacuumed to waste the pool bottom. Our initial readings were as follows:
    FC=0
    PH=7.0
    TA=90
    CH=190
    CYA=0 Not registering on test

    We started running the pump full-time on Sunday and on Monday, we added 2 lbs of stabilizer to raise the CYA up to 30, 1 gal of 10% bleach to shock it and 4 oz of algecide. Didn't try to raise the PH yet. Since Monday, I've been trying to maintain the FC at 6. The water went from green to white to blue but is still cloudy, though it seems to be improving. Yesterday, the FC level had only lost .5 over a 7-hour period and lost 1.5 between 6 PM yesterday and 9 AM today.

    My questions are ...
    Do I need to go back and maintain the FC at shock level until it passes the overnight test or just keep maintaining the FC at 6 like I'm doing now? Is anything else we need to do?

    Thank you so much!

    What is your CC?

    Yes, passes OCLT, CC<0.5, and water is crystal clear.

    Stop using the algaecide. We generally don't recommend it for pool cleanups (or maintenance) here. Once you have algae, chlorine is much more effective.

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.

    Thanks for the info!
    CC = .05
    I've gone back to maintaining at shock level, so hopefully it will clear up now.
