    Have been having algae problems

    I too am new to pool ownership. I bought my house with a SWG and have been having algae problems. They come up as spots on the walls of the pool. Per the advice of Leslie's, I have shocked on multiple occasions and it keeps coming back. Now I'm going to try the TFP method to see if that helps.

    I do have a question tho, since I have a SWG how should I go about raising my FC level?

    Thanks

    Welcome!

    You won't be able to raise the FC level high enough fast enough using the SWG. You'll need bleach. And a proper test kit. The instructions are all here in Shock Level And Maintain

    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!

    Re: Have been having algae problems

    Hello there! You have a great first step-Finding TFP!

    You next step is to find a good, local, cheap bleach source.

    Then order a GOOD test kit. See my siggy below to see what test kit you want BUT I think you need to XL one since you are going to need to SLAM.

    Good luck! Let us know when your test kit comes in so we can guide you through them.

    Thanks all for your help.

    I wasn't sure if I can add bleach since I have a SWG.

    I will begin SLAMMING right now (off to get some bleach). See my test results below

    Don't forget to grab some acid to lower your PH ! The low 7's for the SLAM. What test kit are you using ? 😎

    Re: Have been having algae problems

    I just added acid to lower the PH.

    How long do I have to wait to test the PH again?

    You should be able to retest in 20 mins. Make sure pump is running. 😎

    Re: Have been having algae problems

    One more question before I start to SLAM.

    The Chlorine/CYA chart starts at a CYA level of 60. Mine is currently at 50.

    What should my shock level be? FC of 20?

    Thanks

    Yep your shock level is 20. Shock level on both non SWG pools and SWG pools is the same. 😎

    Re: Have been having algae problems

    Just added 2.5 gallons of liquid chlorine. Hopefully it's not too late in the night to start the process

    Have been having algae problems

    Your fine starting at night. I recommend starting a SLAM at night. During the summer starting as soon as the sun is off the pool. This takes the sun out of the equation, no FC burn off from the sun. That way all the chlorine can be used to start killing algae and get a good head start on it. 😎

    Re: Have been having algae problems

    Not too late. Check it in an hour and redo as needed. Depending on the FC drop you will want to do it every hour until you go to bed. Big drop=every hour, little drop=every other hour.

    Check it as soon as you get up in the morning.

    Test and dose at least 3 times a day. The more you keep it at SLAM levels the faster it will go.

    I hope it goes fast for you!

    Re: Have been having algae problems

    Make sure you turn off the SWG while you are chlorinating manually, or you will end up with more than you bargained for!

    Re: Have been having algae problems

    Welcome to the forum Dustballs

    Or, leave the SWG on since the pool will be using it up anyway. Since his first set of results has the FC at 0.0 it's unlikely it's generating much. Once the SLAM is done they will need to crank it up some and or run the pump longer daily. That and bring up the CYA AFTER the SLAM.
    The only time you really need to make sure the SWG is off is when you do your overnight chlorine loss test (OCLT).

    Thanks.

    I turned it off about an hour ago. Will turn it back on in the morning.

    Re: Have been having algae problems

    It's one of those things were you'll get different opinions and I used to say shut it off during a SLAM and then someone pointed out an error in my thinking. That and the fact that you have the SWG already, why not use it and cut back on some of the bleach you'll need to carry in !! Made sense to me.

    Re: Have been having algae problems

    It's not an error to turn the SWG off during a SLAM. I always recommend turning it off or leave it up to the OP to turn it off or leave it on. I don't see it makes a huge difference in how bleach is saved. 😎
