Question about Intex Automatic Salt Water System for Above Ground Saltwater Pool

Green water with salt water filtration system- HELP

We have a 16x48 above ground pool. We recently put in a intex saltwater filtration system. (last week) It was green beforehand, and has remained green since. We initially added 120 pounds of pool salt. I tested the PH and it was 8.0 so we added muriatic acid to it which brought it down. the water remained green. I added a pkg of shock it and ran the filter overnight, it improved it, to a lighter shade of green but no more. PH is still ok, running salt filter 6 hours a day. Filtration system alarmed low salt yesterday so I added 80 pounds more salt. I added stabilizer earlier this week as well as algaecide. Despite all of this, the water remains light green. the test strips I did yesterday before adding more salt and stabilizer were: Free chlorine 2ppm, ph 7.6, and total alkalinity 80ppm. Any help would be appreciated.

    Wow, imagine my suprise when after a week of being sick and dealing with sick kids I log into to leave you a nice comment about how my pool is doing and thank you for your help(I didnt even see the thing about rating you before now, FYI) and along with your previously helpful comments I see this last hateful one. Thanks so much for all of your help, not so much for calling me an A**hole.

You can not blindly just add salt
you need a salt test kit that reads #'s, not color
Get your salt content to as close to 3000ppm as you can any lower than 2800 and you will not produce enough chlorine and any more than 3500 and it will taste bad and could make your water cloudy or trigger high salt alarms
Also remeber to run filter only for 24 hours after adding salt

you also need to realize that a pool goes green for many reasons lack of sanitizer,heat,sun,rain,sun tan oil, 3 of swimmers
A pool need to be turned over at the bare minimum of 3-4 times in a day.
Intex filters are not sufficient to properly do the task
only a good sand filter and seperate pump of about 1 horse will really keep a pool sufficiently cleand but if you follow my advise you can do it with the intex
lets start with the filtering I believe your pool is around 5000 gl

if you have a 2000 gl ph pump then you need to be filtering 7 1/2 -10 hours just to keep your pool clear you do the math for you
as for grnerating your chlorine time varies depending on the situations I mentioned earlier
it is good you are using a stabilizer but that only goes so far if it was hot and sunny and a lot of use chlorine will get ate up any way
And make sure your algaecide is a non foaming kind and stick to the directions
now to your problem at hand
you now need to as you did shock it but you also need to use a lot of elbow grease and remeber this is going to be tedius

Clean your cartridge with the garden hose blast it in the folds as hard as you can
start your filter again and now add 2 gallons of chlorine or house hold bleach

let filter for 12 hours and then with a pool brush not the bristles under your vacuum head scrub the sides and walls continue filtering until you see the settled algae and then vacuum

now clean your cartridge again and repeat if the chlorine is still high you do not need to add but if it went low again then add 1 more gallon

continue doing this until you can see a huge difference
once you can then start with your algaecide again
at this point overdose it as directed on the bottle once your chlorine is low enough to get in then you need to get in and brush under the seems
with the intex liner there are too many seams and folds that need to be addressed

another hint is to have 2 filters one drying while the other is in the unit
a wet freshly cleaned filter does not work and trap particles as well as one that has been dried

Another good chemical to use is a water clarifier this helps minute particles that you can not see clump together thus making it easier for thr cartridge to trap

good luck and if you have any more questions you can e-mail me through this site

Testimonial: "Was very helpful, very knowledgeable, unfortunately fairly impatient about being "rated" and called me an A**hole because I hadnt yet rated him due to being sick. (and the fact that I didnt know I even needed to) Thanks for the advice though!"

    I forgot to mention FYI a salt system does not keep your pool cleaner it is just a means of not having to phisically add liquid chlorine or tablets

    I also didnt let you know that I run my filter 24/7 either generating or just str8 filtering

    It is no worse than running a 40 bulb all day

    any way once you get it situated you should swap filters every 1-2 days and leave the filter running

    yes even when it is being used just dont run the generator with people in it

I am having problems with the copper levels in my 16X48 above ground pool with intex salt water system. what chemical do I need to purchase to bring these levels down?


You need a sequestering agent to get the metal out. Get a quart at your professional pool supply house and follow the container instructions.

For best results, chlorine should be at minimum or at zero.

Before you do this ... does your pool have a heater attached? What is the pH? If there is a heater and the pH is below 7.0, the water could be eating the copper jacket in the heater. Make the pH right before you do anything. pH should be at 7.2

If my pool has an algae problem now . can i convert to a saltwater filtration system w/o draining the pool ?


You need to rid the pool from algee. When you say saltwater filtration do you mean a chlorene generator? It generates chlorene from the sodium chloride that you maintain in pool. This still means you need chlorene to kill the algee. Shock the pool with chlorene shock. After allowing the pump filter to mix, let stand ovenight. Vacuum green slime from bottom to waste. Your pool supplier can help you . Kill the algee then start up chlorene generator.

We recently purchased the intex saltwater system for our above ground pool. We read all the instructions and followed them however our water is still cloudy and a light shade of green. what can we do


You need a sequestering agent to remove the metal from your water ... let the chlorine go to nothing ... put in some 'metal out' or similar according to the instructions on the container ... then start again with the chlorine.

Chlorine and copper and/or iron = green water

My intex saltwater system green light then low salt light


You need to add salt to the water. How much depends on what size pool you have. Your owner's manual will tell you exactly how much to add when the low salt light comes on. On my Intex I would need to add 35 lbs.
