    Slamming question

    Before switching to the BBB method, I would "shock" my pool weekly. If my pool is clear and my chemistry is perfect, do I really need to slam my pool? Also, I'm curious to know how much bleach others are adding daily to a IG 20,000 gal vinyl pool.

    No need for a weekly "shock". Only SLAM when there is a problem.

    Normal to have to add 2-4ppm per day ... depends on a lot of factors.

    Slamming question

    There is no need to SLAM your pool unless you have algae. As long as you keep your FC in range for your CYA level you won't have algae.
    I can't tell you how much bleach your pool will need on a daily basis. What's your CYA level now ?
    On my pool I add roughly a quart of bleach a day. Sometimes a quart and a half.
