I assume you have a heater...the green is from the high copper content in your water reacting with the chlorine. Get your pH up as soon as possible and get a copper reading on the water. Assuming it is high you will need a metal-out product from a local pool store. We prefer the Natural Chemistry line of products in our service company.

Water in pool seems cloudy now


If it seems clowdy now it is probably low on chlorine and unless this is corrected it will turn green in within a day or two. My suggestion is that you bring a sample of your water to a pool supply store and they will test it. If you have filled the pool recently with new water the two things you should be most concerned about are chlorine, stabilizer ph and alkalinity. Since your pool is clowdy the chlorine should be about 10 ppm and the stabilizer should be between 30 and 50 ppm. If you are short on stabilizer the chlorine will be gone very soon. If you have too much stabilizer the chlorine will say in the pool but it won't be as effective. Since the water is new the ph and alkalinity should be ok but the source of your water might be poor. Alkalinity is based on the amount of sodium bicarbonate (baking soda) in the water. If the level is right it helps keep the ph stable. Most municipalities supply water with 80 ppm of sodium bicarbonate in order to maintain their ph more easily. If the ph is too high it is base and causes the chlorine to be not as effective and it causes other problems when it is too low. Adding acid to the pool reduces the ph and adding sodium carbonate or sodium bicarbonate increases the ph. Since the water is new I would automatically shock the pool to 10 ppm of chlorine and treat with stabilizer to 30 ppm and then see how it goes. I wouldn't let anyone swim until the chlorine drops to between 2 and 4 ppm, the pool bottom is clearly visible and no dirt, etc is visible. I hope this helps.

If your salt is at the correct levels required for your pool and your still getting the "91" code on your LCD screen do not add more salt you need to clean the plates on the chlorinator. Look at your manual and it gives you instructions on how to remove, clean, and replace the chlorinator section on the pump. Reminder, if your PH and/or alkalinity levels are off you'll be cleaning the plates often because of the scale build up. I personally run my pump 4 hrs daily and I have never had a problem with green water however, once it did become cloudy (white) I began treating with algaecide and changing filter every 3 hrs. It cleared it right up. I love the Krystal Clear System.

Green water with salt water filtration system- HELP


you can not blindly just add salt
you need a salt test kit that reads #'s, not color
Get your salt content to as close to 3000ppm as you can any lower than 2800 and you will not produce enough chlorine and any more than 3500 and it will taste bad and could make your water cloudy or trigger high salt alarms
Also remeber to run filter only for 24 hours after adding salt

you also need to realize that a pool goes green for many reasons lack of sanitizer,heat,sun,rain,sun tan oil, 3 of swimmers
A pool need to be turned over at the bare minimum of 3-4 times in a day.
Intex filters are not sufficient to properly do the task
only a good sand filter and seperate pump of about 1 horse will really keep a pool sufficiently cleand but if you follow my advise you can do it with the intex
lets start with the filtering I believe your pool is around 5000 gl

if you have a 2000 gl ph pump then you need to be filtering 7 1/2 -10 hours just to keep your pool clear you do the math for you
as for grnerating your chlorine time varies depending on the situations I mentioned earlier
it is good you are using a stabilizer but that only goes so far if it was hot and sunny and a lot of use chlorine will get ate up any way
And make sure your algaecide is a non foaming kind and stick to the directions
now to your problem at hand
you now need to as you did shock it but you also need to use a lot of elbow grease and remeber this is going to be tedius

Clean your cartridge with the garden hose blast it in the folds as hard as you can
start your filter again and now add 2 gallons of chlorine or house hold bleach

let filter for 12 hours and then with a pool brush not the bristles under your vacuum head scrub the sides and walls continue filtering until you see the settled algae and then vacuum

now clean your cartridge again and repeat if the chlorine is still high you do not need to add but if it went low again then add 1 more gallon

continue doing this until you can see a huge difference
once you can then start with your algaecide again
at this point overdose it as directed on the bottle once your chlorine is low enough to get in then you need to get in and brush under the seems
with the intex liner there are too many seams and folds that need to be addressed

another hint is to have 2 filters one drying while the other is in the unit
a wet freshly cleaned filter does not work and trap particles as well as one that has been dried

Another good chemical to use is a water clarifier this helps minute particles that you can not see clump together thus making it easier for thr cartridge to trap

good luck and if you have any more questions you can e-mail me through this site

Yes, you can add chlorine. Liquid chlorine will raise the ph a bit. Don't know what kind of shock you are adding, but wait a day, recheck ph level, than adjust.

Salt water intex pool


Salt chlorine generators cause your pH to raise over time. You will need to add acid as needed to keep it within the ideal range. When adding acid, shoot for the low end (about 7.2) so you have room for the pH to creep up again before needing more acid.

As for green water, what is your chlorine reading, if any? Probably need to shock it not only again but an even bigger dose than the first. Shock treatments are not cumulative. If the first doesn't do the job, adding just a little more will not either.

CLOUDY SALT WATER POOL


salt does not solve your problem.
People do no realize that all the salt does for you is that it eliminates having to pour regular chlorine in.
Everything else stays the same as a normal pool with just plain ole h2o

The dilema is that intex filters are to small for the job that needs done especially in your case now that you have the dreaded green monster

your solution is to first get it cleared up
shock your pool with 2 gallons of liquid chlorine and then filter filter filter
You will need to brush the dead algea and vaccum once or twice a day for a couple of days and you must clean that cartridge 3-4 times a day with the garden hose
you will be surprised how much green it will trap

once pool starts to clear and the chlorine level starts to come back down from Mars you can start using your generator again.
you will need to find the amount of time thatorks for you but 3-4 hours will not cut it in the hot weeks

Chlorine consumption is due to #of bathers, heat ,sun, rain so any given day will dictate a different amount of generation needed keep it high so you do not get algea again about 3.0

you also got algea because you were not stiring up the pool enough you again need to filter filter filter every day
try to find some of my other postings with more specifics

I have a 18ft x 52 intex pool with salt water chlorinator.green


although you may or may not have enough chlorine in your pool you must also realize that a pool need turned over at least 3 times a day.
an example is if you have 7000gl of water and a 2000gph pump you need to filter at least 10 hours or so.
More important than chlorine is the actual circulation of the water you can have all the chlorine in the world but if you do not have the circulation the water will become cloudy or green this also happens when you have no swimmers for days at a time


the filtration time is over and above the chlorine generating time your 4 hours a night for generating chlorine sound like you are guessing sometimes it may be 4 and sometimes 2 or 6
it depends on # of swimmers a day sun and what was in the pool to start

It is important to have a test kit for ph and chlorine and keep chlorine at 1.0to 1.5 now set your ph
ph will rise and fall with your chlorine level one you have them set good at the first time then ph should stay safe enough and re level as chlorine is kept right

also remeber that the wrong ph causes more problems than wrong chlorine levels

Also make sure your salt is no more than 3000ppm and no higher like some people recommend and no lower than 2500 test kits are available for 10 dollars

all of this can be found on intex.com either in a video or pdf files for water capacity and approximate time for generating chlorine.


to be sure always use test kits

Water is cloudy in easy set pool. How do I clear


not enough info like what kind of chlorine and if salt water set up Cloudy water is usually not enough filtering or low chlorine for an extended period of time Be more specific.

No matter what method salt or regular water you need to turn the pool water over at least 3 times a day/night

Lets use generic #'s if you have a 4000gl pool and a 2000gph pump you need to filter at least 6 hours you will need to adjust the #'s for you and figure out how long to filter.

It is also important to keep the chlorine between 1.0 and 1.5 then set your ph level with either ph up or ph down depending on what yours registers at after the chlorine is set.

Remeber that you must first set the chlorine since the ph is affected by chlorine level.

once both are set then the ph will go up and down with your chlorine so keep it in check after initial setting

for now add a little extra chlorine and filter for 24 hours then vaccum remeber to take out the filter cartridge once or twice a week and hose it hard with the garden hose. I am on my 3rd season with the same cartridge

high chlorine can cause problems too it will give false readings for your ph and alkalinity.
The most important thing to remeber is that there is a sequence to follow.
First buy a test kit for salt about 11 bucks for 10 tests. you need to have the ppm's at 3000
if it is to high drain 20% water re-fill and filter/curculate for 6 hours then test again. once at 3000 then go for your chlorine it should be between 1.0 and 1.5 with a test kit now with those 2 in line go for ph adjustment ph should be as close 2 7.6 as possible. Ph will cause more problems like cloudy water or algea more than anything else.
another thing you need to realize is that the intex salt system sucks. Once you set it for the # of hours to chlorinate you are basically guessing as to what is needed. Yes there is a guidence chart as to hours to run but it is over kill and lets too much chlorine be generated start with 3-4 hours of generating but remember also that at 4 hours generating that is nowhere near enough filtering
you will need to shut power off get it out of sleep mode and continue to filter
on avberage a pool should be turned over 3 times a day my pool 7000gl and the 2000gph all in one intex salt pump needs run at least 10 hours a day alone without the chlorinator
my pool only 18' so with your total gallons it will be longer
one last thing to consider is that when in chlorine generating mode the filter slows down because of all the electronics. You can not hear it happen but if you put your hand in front of the discharge you can tell
