    Slamming away....

    Started the slam process on Tuesday...my cya is 80 and I have 38 as my fc. Cc is .5 I am beginning to see outline of my drain in deep end. Only lost .5 of chlorine over night. My question is do I keep the free chlorine level up by adding more bleach in the morning and night since water is still greenish in deep end and cloudy in shallow? Or should I just give it more time to clear? My guess is to keep adding but didn't want to cause harm to pool by keeping levels so high...thoughts??

    Your instinct is correct - keep adding and maintain that SLAM/Shock FC level until you do indeed pass all 3 SLAM criteria. Even when the water starts to look clear, don't stop with any of the SLAM requirements until you pass. Algae is quite resilient and can return if you let-up. Good luck!

    It won't cause harm to equipment and liner to keep that high correct?

    As far as I understand, as long as your FC and CYA are within normal tolerances for their relationship, there should be no issues.

    Kevin is correct. The CYA in your pool not only protects the FC from the sun, but also serves to protect the pool and swimmers from the effects of chlorine as long as they are balanced together as noted on the Chlorine/CYA Chart (link below). Have a nice day.

    Do what you can to improve circulation in the deep end. If you can point a return eyeball down, do it. Open the main drain if you have one. If not, connect the vacuum and tilt in sideways or upside down so it acts as a main drain. You want whatever is suspended in the water into the filter so it can get removed. And don't neglect brushing and those hiding places like inside ladders. Water problems

    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!

    Thanks guys appreciate it. Didn't think about turning the vacuum upside down.
