Salt water intex pool

I would suggest that you keep your salt level around 2,5 for chlorination, however to get the green pool sorted your pool needs to be shocked and would recommenced to get your pool's free chlorine level at least up to around 5 in order to shock the pool as normal free chlorine level should be 3

It has been 15 years since I owned a pool. My best way was to shock pool with a liquid shock , run filter for a day then broadcast aluminum sulfate with filter off. Usually in a day or two all debris is on bottom of pool. This debris must be vacuumed to waste because it will clog the filter.

get in the pool companies to adjust the levels to correct and remove the alge growing in the water

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.

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

you will need to do a few things.
Start by shocking the pool and then in 12 hours or so you will need to brush the sides and bottom
Now wait a few hours for the pool to settle and vacum
now clean out your cartridge and start filtering without the generator.
Now add in some liquid non foaming algecide
Now a day later repeat the brushing then vacum again clean filter and reapeat till your pool clears
Remeber to add a good stabilizer so that the chlorine that is generated holds longer and get test strips that read #'s to test salt you want to have the salt as close to 3000ppm as possible
Once pool is clear continue to use the non foaming algecide every week

Drain this pool, give it a good cleaning and start over. Clean the electrolytic cell. Your 24" x 52" size pool holds 12,481 gallons of water and requires 310 pounds of salt at initial startup. You should set the timer to run 11 hours per day. If the low salt light comes on add 85 pounds. You need an owner's manual.

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.

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
