First of all, STRIPS!! most unreliable pool equipment ever. Take a small bottle of water to Leslies pool supply and they will read it for free. if its Black dots or blotches it could be blue/green algae its resistant to chlorine and a pain to get rid of. Or if your pool is vinyl over time in high traffic areas or places dirt gets stuck and gets rubbed in could discolor the vinyl. If its algae its basically maintaining propper chemical balance as usual and scrubbing the heck out of it daily with a harder brush type. Harder sythetic brush for vinyl and plastics and steel brush for plaster.

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: High PH and ALK
Yes you can. You need to lower the Alkalinty by adding the Muriatic acid in colums in the deep end of the pool. Then address the ph. It will come down somewhat with the lowering of the Alkalinity.

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.

Have you had a lot of rain?
Rain will make ph go up
too much chlorine can produse Hi ph
Just keep treating with ph down ti'll you reach 7.2-7.8
As for the test strips you only need to dip and pull out
then wait 10 seconds and compare
