Thread: Cloudy/muddy water problem.

  1. Back To Top    #1

    Cloudy/muddy water problem.

    Well, this is my second year using the bbb method, and it has worked quiet well, until now. I went on a vacation to another state for a week, and somehow the pump got unplugged. And from that, algae started to grow. So, after i got back, i started working on getting rid of the algae. I stopped using bleach, and am using shock, because in my area it is cheaper then bleach. So after about two weeks, the algae was almost gone, but the water was incredibly cloudy. (I also bought a chlorine tablet to keep the chlorine up, witch i should have done before i left.) Now, as i was taking out the filter to clean it (cartridge) when i pulled it out, mud looking water came out with it! I don't know if it is dirt, or something else, (dead algae maybe???) And, as i was cleaning the filter, milk coloured water came out. Now, this filter was two weeks old, and for me, a two week old filter has a brown colour to it. This one was pure white! Plus, the pool doesn't seem to be improving. Can someone tell me what this white looking stuff is, why my pool is cloudy, and not getting better. Also, what am i doing wrong????

    P.S. after i got back no one was allowed to swim in it, so not as much strain on the pump and filter, plus it looks a little scarry swimming in...

    What is in the "shock" (take a look at the label)?

    Likely dead algae or possibly calcium build up if you have been using cal-hypo (or have high calcium hardness for another reason).

    Make sure you review the shocking process. On tpf, shocking a pool is not a product labeled "shock" but instead is a process of raising your chlorine level to a high level (depending on your cya level) and holding it there until the criteria in the link above are met.

    I don't use cal-hypo, only muradic acid ( I always have high alk. and PH.) Pool Shock and swim, and the cya acid/stabilizer. But, looking at the main ingredients in the shock, Calcium Hypochlorite... So i guess i am using cal-hypo. Hm. Should i stop using it? I don't want to buy bleach, it is fairly expensive where i live...

    Cal Hypo isn't inherently bad. We need test results though. Your CH might be too high and Cal Hypo is adding to it.

    Just a guess, but that stuff in your cartridge sure looks like residual calcium from using excess cal-hypo.

    It depends on what your CH level and other test results are. Please post a full set of test results: FC, CC, ph, TA, CH, and cya. See: http://www.troublefreepool.com/what-...ns-t10341.html

    Where do you live and how much is it? Another option is liquid chlorine (high concentration bleach) typically at 10 or 12.5% sodium hypochlorite (verse 6% sodium hypochlorite in bleach).

    so, test total chlorine, alk, ph, and, should i test hardness? i would guess it is high, but i heard it only matters with hot tubs and such.

    Re: Cloudy/muddy water problem.

    We certainly need Calcium Hardness levels. Too low doesn't matter in a vinyl pool, but too high and you'll get calcium deposits.

    Re: Cloudy/muddy water problem.

    ok, here we go
    CYA:25ppm
    Total Chlorine:5ppm
    sorry, don't have free chlorine or combined chlorine tests.
    pH:8.2
    Alk:200ppm
    Total Hardness: um, when i added the hardness indicator, it turned yellow/transparent.

    I am getting a bunch of them.

    As I understand it, the HTH CH test (that is the one you have?) has more trouble with interferants. As you add drops, the color will probably turn to green, indicating your CH level.

    Re: Cloudy/muddy water problem.

    Assuming your CH level is high, it is not surprising at your high ph and higher TA levels, that you are getting calcium buildup and potential clouding in your pool/filter. First thing to do is to drop the ph level down to 7.2-7.4 and attempt to keep it there.

    I have the HtH 6 way test kit. Test total chlorine, bromine,pH, total alk., total hardness, cya.

    The thing is, no matter how much acid i add, it always remains up. It was like that last year to. And i used bleach then. ounce, i added half a gallon of acid, (yes, i know, very bad idea) checked it next week, it lowered it by about 5 ppm. And it is a 15 ft by 4 ft round pool

    Re: Cloudy/muddy water problem.

    Make sure your FC (or in your case TC) level is always below 10 ppm when testing the ph since FC above 10 ppm makes the ph inaccurate and causes it to read high. When testing ph, do it before adding chlorine to the pool.

    ok, I'll keep that in mind. my test only goes up to 5ppm though...

    Speaking of which, when are you going to get a big boy kit

    I have experimented with the OTO test and when my FAS-DPD FC chlorine test is indicating 10...testing with the OTO and getting deep yellow could still be confused with 5 on it's scale.

    Re: Cloudy/muddy water problem.

    How big is the pool? It is hard to say how much is too much acid not knowing the size. With FC > 10ppm (not sure what you are at if your test only goes to 5ppm) the pH will read artificially high. But, if the FC < 10ppm and the pH reads 8.2 ... that could mean it is ANYTHING > 8.2ppm. It may take a LOT of acid to get it down into range. That is your first step.

    Also, are you SURE that the amount of FC that is added by the cal-hypo is actually cheaper than the 6% bleach? Give us the prices and quantities of each and we can tell you which will add the FC for the cheapest cost.

    Oh yeah ... I too have to recommend investing in one of the recommended test kits so you can sure of your pool's chemical levels.

    Not many of us here are either. Not having a proper test kit ends up wasting more money down the road.
