Ph level too high in my Intex Saltwater System Pool. How long do I hold the 3-way test strip in the water before reading? I have added the proper amount of ph lower 3 times and it is still high. I hold it in for 3 seconds then hold horizontal and compare to color chart. Should I hold it in longer?

sounds likebad salinity sensor

I am having the same problem I wonder how to tell if my salt water system is working. My ph is good but I still have no chlorine or copper

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

I sometimes have the same issue with mine.. One thing missing that helps protect the chlorine from burning off in the heavy sun is (Cyanuric Acid)or (CYA) You should be around 30-50ppm.. To bring this level up to 30-50, they sell a conditioner that raises this level.. Don't add too much if your already close to the 30-50ppm.. Other than that, you can continue to run the system as you already do.. Seems like it's maintaining clean and clear... Hope this helps???

For starters I would bring a sample of your water to a pool store and they usually test it for free. They will then make recommendations. Be certain that everything you add to a pool is necessary based on the test results. If you are draining or partially draing the pool then sometimes chemicals recommended by the pool supply store will not be necessary. The following is what I would do to keep a pool blue:
1. Make sure salt is at the recommended concentration.
2. Only shock the pool to if the chloring level has droped below about 2 ppm.
3. Place the recomended dose of stabilizer in the pool.
4. Make sure pump and filter are working properly.
5. Check the pool chemistry on a daily basis for about a week to. I recommend test strips that at least measure chlorine, Ph and stabilizer.
6. Check the chemistry on a weekly basis and clean the pool and equipment according to the pool instructions.

Smile, you are a pool manager.

Heather,
leave it alone for a week
If it is still high then get a bottle of ph down.
Make sure you go slow otherwise you might find yourself needing to boost it again.

You are going to need to buy chemicals anyway (acid for sure and probably algaecide) so find a good pool store tech and have them test your water and recommend the proper doses.

In summary though, you should not taste the salt in the pool and being able to means the salt content is to high. Chlorine generators will not work if the salt is to high and the fix is to drain water and dilute the remaining water until the salt content is no higher than max. No chlorine could explain the algae.

Generators also cause the pH to rise over time so you will need to keep acid on hand to counteract that.

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

I use my 3 way test strips and copper strip when the pool is not running After 15 seconds the readings are using a bit high. After 3 - 4 minutes the readings are perfect.
