SOURCE: I have an intex chlorinator and an intex 24' x 48

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

SOURCE: 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

SOURCE: Low flow indicator light comes on chronically.

If you have excessive calcium in your pool the calcium will solidify on your titanium plates. Look for little bits of white scale (looks like paint chips) in the pool usually by the outflow. To fix, unplug the chlorinator, remove the inflow and outflow hoses from the chlorinator, also remove the flow meter (piece of pipe that has the wire attached to it. Look in at the titanium plates. If it has white calcium coating it, then flush with the hose till it all comes off, if it doesn't come off remove that piece of PVC and soak in vinegar (haven't had to do that but thats what the manual says). Manuall says to drain 25% of your pool and refill with fresh water but I elected to just keep cleaning it out when the alarm went off untill all the calcium in the water turned to solid (had to clean 3 or 4 times). Be sure and vacuum up the calcium in the pool.

SOURCE: 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

The low salt light is on and is not making chlorine. Salt level topped up yesterday as per pool shop sample. Chlorinator stopped sometime yesterday


the salt light indicates more than low salt level. now that you have eliminated that possibility, if the light is still on, there may be several possible causes. the cell may be dirty, or nearing its end of life, there might be restricted water flow or the water is too cold. these are all easy and inexpensive to check

No flow is red and no chlorine lights indicating chlorine


I assume you are describing a salt system.
Ensure all baskets are cleaned out, filter is clean and proper flow of water.
Check salt cell for calcium buildup.
Beyond that it could need a flow sensor replaced.

Hi, I have a 25sc that keeps telling me there is no waterflo. Yet the water is flowing perfectly well. It also has now turned my pool a nasty brown.m Salt is fine an Ii have added extra chlorine.


looks like you need a new pool guy, check the filter pressure should be well under 20 psi,W/O solar.. get a test kit and test the water or bring a sample of water in a clean jar to your local pool supply and have the test it, also ask them to recommend a salt system pool guy for you ASAP.

Zodiac lm3


The lm series chlorine generator has a tri-sensor inside the cell that measures flow, water temp, and salt level in pool. If the controller is indicating no flow after it has been cleaned properly, then the cell is most likely in need of replacement.

Just purchased and installed Intex salt water system. It shows low flow and now, after 5 days of installment, the water is completely green (expecting Swam Thing to come out!) I need your guidance to...


Seems like you may not have the pump and the salt chlorinator in sync... If your water is dark green and not a big pool, you may want to drain and refill, if you have a large pool, you may want to shock and then try the following...
1.Make sure you have added the correct amount of salt...
2.Set your timer for your pump for 12 hrs.
3.Wait 15 minutes and then turn on your intex salt water system..
4.Set you hrs of operation on your salt water system for 10 to 11 hrs...
5.After running the system for 3 days, check your chlorine level..

If water clears and chlorine level is high, adjust the time.. You will have to re-sync the pump and chlorinator.. If the pump turns off before the chlorinator finishes it's cycle, you will get a "LOW FLOW" alarm..
I hope this helps and good luck.. Please rate and comment on the information provided.

Intex salt water chlorinator I added a higher flow pump and chlorine levels seem low no matter how many hours I run the chlorinator


your pump has nothing to do with chlorine generation.
You need to get a salt test kit that reads in #'s not colors.
Now get your salt to 3000ppm or as close to it as you can.
The amount of salt reccomended in the manual is just a starting point
any lower than 2800 and you will not produce enough sanitizer and over 3600 and your pool can go cloudy, taste bad, and rust metal parts
