Question about Pool & Spa
Have been using granular chlorine always never had this problem before
Changing the sand should do the trick. Those relatively small filters can load up with debris and oils quickly. The pump doesn't always have enough power to effectively rinse out the filter during backwash, especially if the sand is old and loaded.
One thing you may want to do is use a flocculant to drop all the suspended particles to the floor, then vacuum to waste. This will prevent all that dirt from getting into the new sand.

hayward S-180 filter takes 150lbs, S-210 takes 200lbs not familur with the S-200. To change sand you have to remove the vari flow valve on top. You can either unplumb the filter and roll it over on its side and try washing the sand out or try scooping it out upright. Whatever you do dont damage the laterals on the bottom of the filter. When refilling with sand you want to make sure all the laterals are undamaged and in the down position. I always fill the filter half full of water to keep the sand from damaging the laterals while re-filling the filter with sand. Make sure you use pool filter sand and not play sand!

SOURCE: no chlorine reading
Salt is sodium chloride, you can only measure salt levels now as your CL (cloride) is bound to a NA (sodium). Table salt =NACL, Your Intex system will tell you if your salt level is too high or too low but your old test equipment for free chlorine will continue to tell you no chlorine as it can't react with the chloride any longer as it is bound to the salt. That is why they tell you you never have to add more because the salt stabilizes it. Your chlorine is there it's bound to the salt. Use the pool it's fine and it makes your water feel really soft! Just keep the salt level right and your fine> It's confusing as they call the unit a chlorine generator! I had the same issue, called Intex and they told me the above.

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

ok here is the scoop first of all the generator will not raise your PH
Hard water rain and bad pool maintainence raises PH
Yes you need to add chemicals Salt water system is to just not need to physically pour chlorine in
on to your problem, you need to get a test kit and make sure you get your salt to the level it needs to be at ( about 10 bucks for 10 tests)
3000ppm is a good level any higher and you will definately have a salty taste any lower than 2500ppm and your generator will not produce enough chlorine
If you are close but under 3000ppm add 10 pounds of salt at a time till you get to 3000 making sure you filter/curculate only ( no generator ) for at least 24 hours even if you do not see the salt it is not mixed enough
If it is too high then let out 2-4 inches of water re-fill and filter for about 4 hours and then check
once your salt is proper then go on to getting your chlorine level to 1.0-3.0
this will never be achievable on a daily basis so be ready to deal with ph also
chlorine will fluctuate greatly depending on #of swimmers per day, sun light,heat, and rain so as a general guide start out with 4 hours of chlorine generation and see what that does for you for that specific day you may have only needed 2 hours or maybe you needed 6 hours you are the best judge of this once you become familiar with what works for your situation
now for ph it is some what controlled by chlorine level so once you get it set while the chlorine is good the ph will rise and fall with the chlorine level Usually not enough to make a difference unless you have to add hundreds of gallons of water or if you have so much rain that it over flowed your pool so check your level and either use ph up or down for your situation you need to be close to 7.4 or so
Now to really address your problem ( ALGEA )
most pool owners do not realize just what it takes or is involved in proper pool care.
A pool will form algea for a # of reasons but if you filter proper;y it will remedy other problems that could occur
first you need to realize that a pools water needs turned over at LEAST 3 times a day ( swimmers or not ) by this I mean (and you gave no specifics on pool size) Lets use generic #'s If you have a 4000gallon pool and a 2000gallon pump you need to run your filter for at least 6 hours you do the math for your size pump and gallons of water
Now this is over and above the chlorine generation so as you see it is important to stay on top of the maintainence especially if no one uses it since that creates curculation
well after all of this add a good chlorine stabilizer and that will help with holding your chlorine level also
JUST REMEMBER FILTER FILTER FILTER
especially since the intex filters are not strong enough for the size pool that comes with it
And I forgot to mention you should spray the paper cartridge with the garden hose on high from top to bottom EVERY DAY

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
