    Safe to swim up to SLAM value of FC for your CYA level. BE SURE you can see the bottom! Especially with little ones.

    Re: Slam

    Just one more question please, when you pass the overnight test will the water just turn crystal clear or do you have to wait until the chlorine values to come down before it gets crystal clear?

    You may not get crystal clear until your filter cat he's up with all the dead particles.

    it really clears up after you & filter remove all dead algae from there. With sand filter this cleanup usually takes several days.

    please get one of the recommended test kits before you start the SLAM (or put its name in your signature). The SLAM is multi- day process where you have to maintain FC at shock level for your CYA so the good test kit is prerequisite for success.

    try to take 'progress' pics over stairs or any other feature providing gradual depth view. If you take them at the same spot/same lighting conditions it makes it easy to see how it goes. Make sure your SWG is off and your pump/filter is on 24/7, brush as often as you can. Good luck and don't hesitate to ask questions .

    backwashing helps when the filter gets clogged with stuff (+15 psi relatively to 'clean' pressure). Backwashing too often actually decreases sand filter performance, they work the best being slightly dirty.

    Backwash when pressure rises 25 percent of normal pressure.

    you need to say that by trying to measure your overnight FC loss- part of OCLT. It will take some time for your sand filter to make it completely clear but FC overnight loss test will tell you right away.

    As woodyp said in post #8 you want to backwash when your PSI is 25% above your normal clean pressure. For example my clean pressure is 12, I don't backwash until about 15/16. But if I see above 16, definitely I backwash.

    Re: Slam

    Like magic. Passed overnight test and water crystal today. I'll post picture later. Gonna keep it up at shock value one more night and make sure it passes again. No cc values either.

    Then what, how do I lower chlorine values?

    Thanks again everyone

    No it has been off since I started slam.
    Now it is staying off until chlorine levels come back down.
