    Project Swamp

    Helping a friend. They are flipping a house and with it came the pool! Pool store told him not to add chemicals until all gunk is out, he was having trouble making progress so I told him about TFP.



    First test:
    FC-3.0
    Ph-6.8

    The pool store sold him this shock. He dumped in 10 gallons.

    2nd test after dumping in shock:
    FC-7.5
    Ph off the charts maybe 10 based on color. It was dark magenta.

    Stumped with why ph went so high. Thinking maybe pool store shock is causing it?

    Here are his pump settings -



    I wasn't sure what setting he should be on? While vacuuming he has to backwash every two hours!


    Happy slamming. Hope to see progress soon!

    I thought it was odd that two hours before he dumped in all of that shock ph was 6.8 so I had gone over to add some borax, but second check had ph off the charts. So it's just from the high chlorine levels? My PH stayed within normal range when I slammed our own pool so just trying to make understand Thank You!

    Re: Project Swamp

    The PH test is invalid when FC is above 10 ppm. Whatever it says is meaningless. PH should have been raised to 7.2 before starting the SLAM, Pool School - SLAM - Shock Level And Maintain. PH below 7.0 can damage equipment and pools. Especially since 6.8 is often the lowest reading in a PH test and in reality it could be much lower than that. I would let FC drop to 9 or 10, adjust PH and resume the SLAM.

    Re: Project Swamp

    I learned about needing to raise the ph after we had already started dumping in bleach. 😞 however even after dumping in 10 jugs of shock, FC was only 7.5 when per second check.

    Re: Project Swamp

    You are probably fighting off some ammonia in the pool. Keep adding FC until it holds. Every 10, 15 minutes if you can.

    Remember to recheck the pH when the FC is low.

    Re: Project Swamp

    Just checked levels..... FC was well over 10. So I am thinking when I checked last night he must have just added it. No change in water color. Psi on pump had dropped from 25 to 20. I am wondering if there is a clog somewhere. The water coming out of the jets isn't very strong.

    Make sure your skimmer isn't full of stuff or your weir isn't stuck. Also check your pump basket, if you have one.

    Algae clogs filters quickly. Clean the filter when the pressure rises 25% over clean pressure.

    Re: Project Swamp

    Thank you! I will check that when I go back this afternoon. There are not any weirs on either skimmer. I'll check for pump basket.

    I was also wondering if he should use the other settings on his pump or just backwash and filter? There is a waste option, and recirculated, and rinse.

    He has been backwashing every 2 hours while vacuuming. I wasn't sure what it meant when psi drops. Could that also indicate a need to backwash as well or possibly a different problem, like a clog somewhere?

    Don't know what I'd do with this site! - Thank You all

    Re: Project Swamp

    Waste is if you want hook up a vacuum and vac to waste. A pressure drop could be a bad gauge or debris blocking flow to the gauge. Don't use recirculate if they have an SWG. It will just send a lot of junk through the plumbing.

    Re: Project Swamp

    Thanks pooldv! I think he was just vacuuming on regular filter setting. Is that bad?

    Re: Project Swamp

    No, it is fine, it just send the junk to the filter to backwash out later. Backwash the filter when the pressure rises 25% above clean pressure.

    Re: Project Swamp

    Day 1 of SLAM complete. I am already seeing a difference. We also pulled out some gunk in the pump and return water pressure is much better!

    Here's today's photo:

    Even better a side by side - really couldn't tell just looking at it but the pictures really do help you see the progress

    Took picture on the left yesterday and 24 hours later the picture on the right. Clear steps and less murky for sure!
