Postby golfer2211k » Fri 28 Sep, 2007 18:50

I :cry: I Have been tring to clear my pools murky water.. super clorinated with chlorine level of up to 3.0 in a 14,000 gal above ground pool... the water is a blue green... with ocasional brown on the bottom that i try to pump into the yard..

i super clorinated
used yellow out
superr clorinated again over 48 hours
ran filter full time..

ive used algae cide
clarifier

still no clear water



my pool levels are

cya 30-50
ph 7.2 - 7.5
alk 120-180


i just dont know what else to do... oh and i pumped out about 2 foot of water when i was trying to get the brown stuff... but it is like it moves around...

With the CYA in the 30-50 range, you need to raise the Free Chlorine (FC) level to 12-20 ppm (basically, to 40% of the CYA level so if you can get a more accurate reading on that, it would be better) and you need to hold that level until there is minimal (<= 1 ppm) drop in FC overnight, minimal (<= 0.5 ppm) Combined Chlorine (CC), and clear water.

An FC level of 3 ppm is not even enough to keep away algae at 50 ppm CYA let alone to shock a pool once it already has an algae bloom. You need to maintain your FC level at an absolute minimum of 7.5% of the CYA level at all times -- better to just target 11.5% of the CYA level just in case.

It would take 44 cups (3.6 96-ounce jugs) of 6% unscented Clorox Regular bleach (or off-brand unscented Ultra bleach) or 22 cups (1.3 gallons) of 12.5% chlorinating liquid to raise the FC in your 14,000 gallon pool by 12 ppm to get to 15 ppm (assuming you start from 3 ppm). You will need to add more chlorine several times a day, especially when you start, as the chlorine will get consumed fighting the algae. The key is to maintain the shock level of chlorine. When adding bleach or chlorinating liquid to any pool, but especially a vinyl pool (as I assume your above-ground pool is vinyl), you must add it VERY slowly over a return flow with the pump running in the deep end (if it has a deep end) and should then brush the area near where you added the chlorine to make sure it gets thoroughly mixed.

If your above-ground pool has no floor drain (and I doubt that it does), then you may need to clear the pool, which will turn cloudy from dead algae, by using OMNI Liquid Floc Plus and then vacuuming to waste, but if you don't have too much algae then it could get cleared by the chlorine and filtration (and cleaning/backwashing the filter) alone. Brush the pool regularly as well.

Ok,, I am very new at this... I really dont know much about the numbers..

i have been following the advise of a pool store near me..

I added more bleach tonight... and the levels are

in the 3-6 range on my little tester

My Ph is alittle above 7.2

and the alk is sort of hard to get a reading.. im thinking 30--50 range..

I put a sock on my skimmer filter tonight to see if that would help... and i added more algaecide.


My Pool is above ground 24ft pool...no deep end and no bottom drain..

well there is but i would have to get all the algae by it to get it out..
i think they way i am pumping the water out in the yard while vacc.. ing the bottom helps to get rid of some of what is down there.. it is very green when it comes thru the hose..
i can see the changes in color thru the hose.. so i move the vacc to a different spot till i hit algae spot..
i cant really see the bottom is is a blue green murky color and the pool is 4' deep.

I hope you will be patient with me as i learn how to fix my algae problem and learn how to take care of my pool at the same time...
I love the pool and hoped to beable to use it before the weather turns..

thank you for your help and instruction..

but really i dont know much about what you spoke about in the response above..
baby steps please.... thanks..

so if you dont mind breaking down what you said above thank you..

ok i re read again... so you are saying i need to add more bleach to bring my level from 3-6 up to 12-20? and that would turn my tester really red.. right?

ok it is a hour after last post..

My clorine level it deep orange.. my little kits numbers only go up to 10 so and this is much darker... so it should be in the 12-20 range..

checked my ph.. too and it is 7.2

my alk is about 60

cya is now lower that 30 earlier when i tested the water in the test tub was cloudy so you couldnt see the little dot... now it is almost clear..

What type of filter do you have, cartridge? How big is it?
If cartridge you need to clean filter, you can rinse with hose but in future buy filter cleaner and soak in cleaner. When cartridge filter is small a few cleanings may be needed when clearing up water.

If sand filter backwash, DE filter backwash & add DE powder.

Like Chem Geek has stated, keeping your chlorine level above 20ppm and keeping it there will clear algae. Check 2-3 times a day add liquide chlorine to keep boosted & run filter 24/7 until clear.

I have a B size cartridge... looks sort of like paper fiber.... I have been washing it out every day with a hose... i have a extra filter that i have been soaking in algae cide... but you say get cartridge cleaner... i will do that today....

i am taking a water sample to the pool place to check my numbers for me.. and i will get the cleaner then..

and run pump 24/7

i will post the numbers when i get back..

sense it is the B filter you are going to want to change it out once a week and let the other one soak for a hour then rinse and have it ready.
Also it sounds like Intex above ground, do you have the blue protective caps on intake & return line for pool? If you take return line cap off it allows water to flow across pool & gives better circulation.
I suggest buying a bag of DE powder which is cheap, small 5pounder. What you can do is take a handfull and put under water next to intake line and release it into line which will help. You will see the difference when cleaning filter how much more dirt you catch.
For CYA you can wait & see how 20 does for your chlorine level holding. If you need to raise it you can get powdered CYA not granular at pool store and add to bucket of water then add.
