    Light blue cloudy water?

    I have a 22,000 gallon inground pool. I have been fighting an algae problem for quite sometime now. Well now the water is a light blueish color, but I can't quite see the bottom of it. I've vacummed, shocked, added yellow out, clarifier, cleaned the filter, and added some stuff call pool aid. I can almost see the bottom in the shallow end. I had my water tested on friday and everything was fine. Can anyone help?

    First, welcome to the forum.

    From your description, I would guess you have inadequate chlorine levels in your pool.

    If you could post a full set of current test results, that would help us all give you much better advice.

    Welcome to TFP!

    The first step to cleaning up the pool is to stop adding lots of products that you don't need and which will only cause more problems of their own.

    Do you have a complete set of water test numbers? Knowing the chemical levels is critical to proper pool care. There is no better investment in your pool you can make than a high quality water test kit. I recommend the TF Test Kit, see the link in my signature, the Taylor K-2006 is also a good choice.

    The answer to cloudy water is chlorine and a little time. You need to bring the chlorine level up to shock level, but to do that you need to know your CYA level and be able to test high chlorine levels, which brings us back to getting a high quality test kit.

    As per the results of friday.

    PH-7.4
    Alkalinity-100
    Calcium Hardness-160
    Free Available Chlorine-1
    Total Available Chlorine-2

    The guy at the pool store didn't do the CYA

    As Jason said, you need a good test kit so you can stop depending on the ambiguous results from the pool stores

    You have inadequate chlorine levels. How much to put in there is in direct relationship to the amount of CYA in your pool. If you'll get another test with the CYA number, we can all help get you the correct amount of chlorine (it'll be a lot so get plenty of Clorox or liquid chlorine....maybe 20 gallons...you wont waste any, don't worry) in your pool and help get your pool sparkling.

    I tested the CYA with an test kit that I have and the black dot never disappeared so I assume the CYA is less than 20 ppm.

    Yeah, my guess is it is zero as well. Based on that, bring your FC up to 12-15PPM and HOLD IT THERE until your pool clears. I just posted the same advice in a thread started by "carnochanm" Read the entire thread there...your situations are almost identical and you can follow that for further guidance. Once your water is sparkling, we'll help you keep it that way.

    (Edited by TMQ : changed 155 ppm to 15 ppm !!)

    Ok I put the stabilizer into the skimmer and one of the socks went into the piping. I guess it has clogged the pipes, because the water won't circulate. What do I need to do to remedy this problem?

    Your best bet is to get a drain king, open up the pump skimmer basket, remove the basket, put the drain king into the intake pipe and try to flush the blockage back towards the skimmer.

    Well yesterday while it was still running I saw the sock in the pump skimmer basket, but when I turned it off it sucked the sock back into the line. So do I still need the drain king?

    May, maybe not, if you put a garden hose into the skimmer, or just cycle the pump on and off a couple of times, you might be able to wash the sock fully into the pump strainer basket. Still, pushing the sock in either direction will be easier with a drain king.

    Ok. I bought the drain king. I've put it in the skimmer. How long do I let the water run before I should see the sock?

    If it is working it should only take a minute or two.

    I don't know what kind of pool you have, it's a vinyl liner or gunite? I thought I read on here someone said "magic eraser" but not sure. What kind of buildup is it?

    I have a vinyl liner. It's the algea stuff from when the water level was high and now it's dried up and hard. I think that I will try the magic eraser. Thanks.

    How can I get stains off of floor and pool walls. I had algea when I opend the pool so I'm thinking that the algea caused the stains? What should I do?

    Can you post a set of test results? Especially CYA?
