    Help! Rain ruined my algae clean up

    So we just bought a house with an inground pool...The way it looked when we moved in last week...

    Pool by plpinkinsa, on Flickr

    Have no experience and have learned a lot thru trial and error but I'm about to throat punch someone if I can't get this pool cleaned! After a lot of talking to different pool guys and pool stores. From the advice of a pool guy, we used black algae killer and flocked the pool. The next day we could see the bottom!! and dead algae at the bottom...

    We vacuumed to waste once...The next morning, it started raining and has been raining for several days...

    Yesterday the rain stopped and now the water looks like this...

    I'm not sure what to do now...I shocked the pool yesterday and have been running on filter for about 16 hours...I don't know if I should continue to keep my chlorine high and filter...I called the local pool store and the guy is telling me to shock and flock again and then vacuum to waste. Yesterday we tried to vacuum to waste and it wasn't doing anything but pushing the particles around the pool. It didn't seem to be picking anything up...I have a 20,000 gallon pool, with a sand filter...I've been reading a bunch of different methods. I had read before to keep running the filter and it would clear up.

    Well, the pool doesn't care if it's raining

    You should follow the SLAM process in Pool School to a T. It will cure the problem.
    TFP Moderator TF100 Test Kit TF100 TestKit YouTube Channel PoolMath
    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    You are blending advice from different sources and are ending up caught in the middle. You should make a choice on a resource for information and then stick with that source....it'll prevent a lot of the confusion you are experiencing.

    My chlorine test kit only goes up to 5 ppm ...Would this test just the chlorine above 5ppm? http://tftestkits.net/FAS-DPD-Chlorine- ... t-p47.html

    Yes, that is what you need to SLAM the pool. You also need to know your CYA level. Do you have a test kit that can test for CYA?

    If your vacuum stopped picking up anything, sounds like you should backwash your filter to lower the pressure. And proabably at least a couple more times during the SLAM process. Nice polish btw!

    Re: Help! Rain ruined my algae clean up

    If the pool got it right, which is a big if, you need to hold your chlorine at a 24 for several day to go through the SLAM process to get rid of algae.

    Get your own test kit and for get the pool store and read up on pool school in the top right corner.

    Floc only clears up the current issue. Algae will come back until you pass the three SLAM goals.

    I don't think you are done yet. Your water is still quite cloudy (the hose disappears). Review the SLAM process: http://www.troublefreepool.com/pool-...king_your_pool Your are not done until all three criteria (also in my sig) are met simultaneously.

    Re: Help! Rain ruined my algae clean up

    +1 what linen said. Great job so far, but if you quit before you have met all three requirements you will end up right where you started. Around here, clear means you can clearly see a quarter on the bottom of the deepest part of the pool. You'll get there if you keep following SLAM to a T.

    Keep going until you can see what type of screw was used on the floor drain. You will get there.

    Visability has significantly cleared up since I took the photo. Still a work in progress...I now have grass I need to fish out since we recently mowed but can see down to the bottom step. Deep end is still a little cloudy.

    From what I can see, shallow end still looks cloudy too. Regardless, since you are still cloudy in the deep end, I would post a full set of test results. Were you able to get a non-pool store cya reading?

    Re: Help! Rain ruined my algae clean up

    I didn't re-read the whole thread, so I have a few questions. First, have you gotten the recommended test kit yet? If so, have you passed the OCLT and is your CC <.5? If yes, you may want to try adding some DE to your filter.
