CLOUDY BLUE WATER!!

Postby joannelcoq » Sat 22 May, 2010 07:36

I have a cloudy pool due to the cement contractors dripping their mortar into in while fixing the coping brick. I have an inground vinyl pool 22,000 gal. I have shocked 3 times but can never see the bottom. I have vacuumed blindly and have picked up cement chunks and other debris. The water is blue but not clear, ph and alkalinity is good. The total hardness is low and it says I need cyanuric acid but I dont have metals in my pool. Do you think this floc with work? Is it the same as a coagulator ? I vacuum to waste and backwash and keep putting the DE back in. I feel Im wasting all my chemicals. What now? Help !!! Thank you. :crazy:

If filtration isn't clearing the pool, then you could either use a flocculant such as OMNI Liquid Floc Plus and then vacuum-to-waste or you can use a clarifier such as BioGuard Polysheen Blue and then backwash/clean the filter. If there is a LOT of material, then a flocculant is better otherwise your filter will get clogged and need to be backwashed/cleaned several times. If there isn't so much or if you are unable to vacuum to waste then a clarifier may be your only option.

Ok we had extremely cloudy water. All the chemicals were right on so decided to do a Floc from Leslies.
It has clearly helped tremendously but I don't understand how using the polaris to vacuum to waste can possibly clear out the floc. I turned on the polaris to waste and the floc just ended up spreading out all over the pool again and clouding it up. I also backwashed the filter a few times, because I had put floc in the skimmer to clean the sand filter.
The net on the polaris just basically lets the floc go right thru it and spreads it out all over pool again. Am I supposed to use something else to vacuum to waste for floc>\?
Help its hot here in Texas and I want my pool back!

i have used floc and it worked just as the man said, i had no problems. something in your pool is not correct,you claim you cant see the bottom are there any leaves or debris on the bottom. Just out of curiosity,you say you have had your pool 15 years, why do you call yourself pool newbie......

You probably need to maintain a shock level of chlorine in your pool. This requires you to have a good test kit, either the Taylor K-2006 or the TF-100 with the latter kit having more volume of reagents so is comparably priced per test. Read Defeating Algae to learn how to get rid of the cloudiness which is most likely algae in your pool. You should also get a full set of water parameters and put them into The Pool Calculator to make sure that your saturation index isn't too high.

I have dumped 12 bottles of liquid bleach in my pool. 3 every hour. Still no clorine reading! Its still blue and now alittle milky looking when I clean the filter. I can see the bottom of the pool alittle :( I dont know what to do! The pool company dont help! Do I need to leave it alone to let it sit awhile with no pump on. I am ready to give up but my children will be so upset! Please help! I have 3 more bottles of bleach I can put in the pool. Or should I just drain some of the water out! That is what the pool company said. Drain a foot of water out then add more water and start all over. I cant spend more money! HELP please!

Are you just opening the pool after a winter of having the chlorine level get to zero? If so, then bacteria could have converted the Cyanuric Acid (CYA aka stabilizer or conditioner) in the water into ammonia. Are you sure you have no chlorine? If you are using a DPD chlorine test kit (comparing against intensity of pink/red), it will bleach out above 10 ppm FC and make you think you have no chlorine when you actually have a lot. If you use an OTO test kit (comparing against intensity of yellow) it won't bleach out nor will a FAS-DPD test kit which measures up to 50 ppm and is what I was recommending.

If you want to find out how much chlorine it would still take before it starts registering in your pool, you can do a bucket test where every 1/4 teaspoon of 6% bleach in 2 gallons of pool water is 10 ppm FC. You can see how much you need to add before the chlorine starts to register. If it's a huge amount, then you may be better off doing significant water replacement/dilution.

Wow my pool is looking better not completely clear but better. I put all the bleach in then I turned the pump off for 24 hours everything setteled to the bottom. So I vaccumed my pool and let the water drain out the pool to get rid of the mess at the bottom. Of course I couldnt get it all. But most of it. Then I added water, it got cloudy blue again but not as bad. I will vaccum again after letting it settle and redo the process. Hopefully this will do the trick. I also got chemical to replace in the pool but I dont want to add until I get all the nasty out. I hope I am doing the right thing.
