Algae forming in pool

No low salt warning has come on, and the chlorine is low according to test strips and ph is too high. Am i suppose to add chemicals? I thought that was the purpose of the saltwater system is to not have to use chemicals. I have had the system for less than a month, it seems like it should be working better.

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

Chlorine generators will slowly raise the pH over time. You will always need to have acid ready to be added once the readings start getting above 7.6. You should try and maintain it down around 7.2 - 7.4 to allow for mistakes.

As for the generator; can you turn up the rate it generates chlorine? I am not as familiar with the intex but other brands have an adjustment knob to vary the rate chlorine is made.

Salt chlorine generators are nice, but they do not ensure that you will have a completely maintenance free pool. You will still have to adjust certain pool chemicals as needed to ensure that your pool is balanced. The chlorine generator simply takes the place of traditional chlorination methods. You will still need to add stabilizer, or cyanuric acid, to maintain a level of 60-80 ppm. You will also need to make sure that your free chlorine stays between 1-3 ppm. Your pH should stay between 7.2-7.6 (add muriatic acid to lower or soda ash to raise). You alkalinity should stay between 80-120 ppm (baking soda to increase, acid to decrease). Finally, monitor your calcium to make sure that it stays in the 200-400 ppm range. You will enjoy your SWG, but do not expect it to take the place of regular pool maintenance.

Algae removal from Intex Ultraframe pool with salt water/sand pump


Its a very tough strain of black alhae. Shocking the pool with liguid chlorine will do the trick. First lower the ph level by adding muriatic acid(either pool store or local hardware store carries it). This lowers the ph level quickly. Pour it around the edge of the pool. Wait an hour than add the liquid chlorine. Let circulate for 24 hrs than vacuum to waste. The chlorine is more potent when the ph level is lower, thus the use of the acid

My intex saltwater system pool is cloudy


The chlorine level maybe too low and it is allowing algae to start growing.
Check the Ph level, it should be around 7.
Check the chlorine level in the pools water, use your chlorine test kit.
Check the salt levels, make sure it is at the correct concentration, too low a salt level and the Intex will not be able to generate enough chlorine.

Problem is test strips indicate high copper ion (pink) and total alkalinity is low (light tan) Free chlorine is ok (between 0.5 and 1) and ph is good. We have this greenish silt like stuff on the bottom...


1st.. Clean the green (algae) stuff out..
2nd. Clean the filter...
3rd.. Repeat step 1 and 2 until most all the algae is removed..
4rd.. Brush you pool with a pool brush to remove the remaning algae...
5th.. Seems like you have the right chlorine level but not running your filter long enough??? After all steps are completed, run you filter at 8 hrs and your chlorinator between 3 to 6 hrs until your pool clears up.. After that, vacuum again and clean your filter... During the summer months, 4hrs is not enough circulation.. Hope this works for you and good luck.. Please take the time to write a comment if this works for you...Thanks..

My water is cloudy and says salt level low.....it seems salty enough as I can feel and taste it. Is there chemicals I am supposed to be adding or does this system keep it clean all alone just by adding...


While your problems are likely greater than just the salt content in the water I can tell you that if you feel, or more importantly can taste the salt in the water your salt level is WAY TO HIGH, not low. Have the salt level confirmed with an independent test either at a pool store or using a salt tester.

We changed our pool over to salt water four days ago ago and it is cloudy and has green algae in it. It had green algae when we switched. We thought the salt water system would kill it, but it is still...


You don't mention the size of the pool. If this is a above ground small pool ... dump the water, clean the liner and refill it. Remove the metal with a sequestering agent. Get the alkalinity correct. Get the pH correct then add the salt to 3200 ppm.

Chlorine kills algae. Are you sure it is algae and not metal in the water?

pH should be 7.2 to 7.6. Alkalinity should be 100. If a gunnite pool, the calcium should be 300. Salt should be 3200. Cyanuratic acid should be 50+ if this pool is outside (not indoors).

What to do. If this is a big pool, and you are sure this is not metal in the water, I would super chlorinate the pool - take it to 20 or so ppm. Run the filter for at least 24 hours. Watch the pressure ... you will be filtering out a lot of stuff.

Let me know what happens ...

I run the filter pump then turn on the salt water system for 4 hours and test for the chlorine and it is always very low or no chlorine and the ph is always high


pH will always rise over time when using a salt generator. You'll need to periodically add acid to counteract this affect. As far as low chlorine levels try running the system longer...An average pools circulation system is setup to turn over the pool water once in about 8 hours. Running your system longer should lead to a higher chlorine residual and overall cleaner water.

High ph, algea, salty taste


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.

I have an intex chlorinator and an intex 24' x 48" round pool. I added only 250 lbs of salt, but the table said 290 lbs. I never got a "low salt" reading. When the water level got low I added water and...


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
