Green Water From Salt Water Above Ground Pool 16 X 33
by: Peggy Danel (Juliette, GA )

My husband brought the salt water pump and salt from Walmart and changed our pool over to salt. He added more salt and also change the sand to see if it would help, but so far still green.

Please help, we have people coming over this weekend for Father's day.

Thanks for the question Peggy

There's alot here and a few more things I'll need to know.

The question says "salt water pump" so can I assume that means a salt water chlorinator? If so, what kind did your husband purchase? Is it installed correctly and is it producing chlorine? It might just need to be adjusted.

If so, he needs to be sure the salinity is correct. The owner's manual should have that information, but an educated guess would be anywhere between 3000ppm - 4500ppm.

I'd also like to have your chemical readings:

Chlorine, pH, Alkalinity, Calcium Hardness, Cyanuric acid (stabilizer/CYA)

You have a 16 X 33 pool which holds about 21,000 gallons, so this helps.

Easy Set Salt Startup
by: Anonymous

20x12 easy set 3ft depth (still filling). I have added 80lbs salt, 1/2gal liq shock, 5lbs soda, stablizer. I have well water and my pool is clear but green after adding all that 12hrs ago....I have filter pump and salt chlorinator going....The pool store said I shouldn't use the metal out cuz I am using salt chlorinator? Last yr the metal out was the key. If I use metal out product should I disconnect the salt chlorinator? and let it filter?

First, I'd like to have your complete chemical readings, the actual numbers:

Chlorine, CYA (cyanuric acid/stabilizer), pH, Alkalinity, Calcium Hardness, and Metals (iron and copper) and names of any algaecides you may have used along with clarifiers, phosphate removers, and/or flocs. It makes troubleshooting much easier. I also need the kind of filter you have and if it's perfectly running. If not it needs to be.

Salt pools are a little different but it can be done with a few simple procedures. First is to have the CYA a bit higher. Normal pools run 30 - 50ppm but salt pools can handle 70 - 80ppm. Run the FC between 4 - 6ppm. Run the pH between 7.6 - 7.8. More or less and a salt pool won't be balanced. Run the TA between 60 - 80ppm. Normal pools are 80 - 120ppm. The CH should be 150 - 250ppm.

Remember to keep your salinity at the max allowed for your particular cell. Normally it's about 3500 but first check with the owner's manual for the correct range.

I would not use Metal Out and offer Jack's Purple Stuff. It has the same ingredient as other Jack's products, HEDP, or 1-Hydroxyethylidene-1, 1-diphosphonic Acid. LaMotte sells a Sequestrant Test Kit and I recommend using it.

For more detailed answers you can call Jack's line. they're very helpful.

Help please
by: Anonymous

I have a 8000 gallon pool with well water
Ph level is 8.0. I have added a quart of acid,
Still haven't changed. Do I just keep adding more,
Or is there another issue.

Muriatic acid will always lower pH. You need to wait 8 - 10 hours before retesting. This allows the water to fully circulate. Be sure the acid is fresh. And also be sure you're testing correctly. Use a Taylor K-2006 with fresh Reagents for the most accurate readings.

Cloudy water
by: Ernesto

I buoyed a above ground pool 10ft easy set, the box say it holds 960 gallons of water. What is causing the cloudiness, is the chemicals or the filtration? The pump can filtrate 350 gallons per hr. I'm thinking to buy a 1000 gallon pump to help the filtration system. What of your E books you recommend?

Hi Ernesto. It's great you bought a pool and I'm sure it will bring you years of enjoyment. Taking care of a pool is simple but there are things you need to do. Concerning the eBooks. I recommend Clear Blue Pool and Solutions To Common Pool Water Problems. Study those and you'll be on your way. You can find the links below:
