  • Calculate your gallons of the vessel.
    • On Avg. 15' x 4' pool = 5,000 - 5,500 gallons
    • Then identify current level of salt.
  • If 0 - you will need about 150 lbs to bring to minimum 3200 ppm

Is that 15 measurement a circumference (around) or diameter (across) - it makes a large difference. New measurement should be diameter.

Model CS8111 ... How much salt do i put in an Intex Easy Set Up Pool 15 x 48" for the 1st time?

The ideal salt level is between 2500-3000 ppm (parts per million) for this model - the optimal level is 3000ppm.
For a round pool with your dimensions of 15 feet across and 48" deep, with the water at 80% capacity (it's not filled to the top right?) = 3736 gallons. So the amount of salt you need to add initially to get to 3000ppm is 95 lbs of salt.
When low salt is detected (Code 91) you are supposed to add 20 lbs of salt (what the manual says).
Here is a link to the manual that I found : (see page 133)

How much salt is needed for a 30 ft diam pool with 54 in side walls?

23,790 gallons if you fill it to the very top.

Calculate the volume of a pool you need the radius^2 times pi times depth times 7.48 to come up with gallons.

Radius = 15ft
pi = 3.14
depth = 4.5ft

15^2 x 3.14 x 4.5 x 7.48 = 23780.79 or 23,781 gallons.

So the salt you need is 640 lbs @ 40lbs each = to 16 bags

I don't think Mike's figures are correct according to my research. You can ask at a pool supply shop, who will also sell you the salt. It certainly is going to be 32oz to make a saline pool. Remember the salt is doing the job of chlorine to kill bacteria.

My pool is cloudy and I added clarifier and it still won't clear. I checked the salt count and it's reading 1100 ppm. We have a 15 foot round 48 inch deep pool. I also shock the pool weekly...

1st... Your salt count should be at 3000 ppm... For your size pool, the start-up salt needed should be about 95 to 110 lbs..
2nd... Run your pump for 24 hrs without the chlorinator after you have reached the 3000 ppm to properly disolve the salt and use only "pool salt"
3rd... Set your pump at 12 hrs and your chlorinator at 10 to 11 of those hrs until you have reached the desired chlorine level.
4th.. After your pool water has cleared, within 2 to 3 days...clean your chlorinator electrolytic cell and adjust your time down to maintain the proper chlorine level..

Hope this helps and if it does, please rate and comment....
Good Luck!!!

I just need to know how to set the salt water system. i have an 18ft pool and have put 3 bags of salt in so far.

You don't say how deep it is. Since you say 18 foot pool, I presume it is round. AT 2 foot depth = 3817; 3 foot depth = 5726 gallons; 4 foot depth 7634; 5 foot depth is 9543. Your salt bag should tell you how much to put in referencing the gallons.

I hope this helps. Thanks for using

I have an above ground pool 18' round 52" deep. I purchased the intex saltwater system. I have had it run everyday for 8hrs a day and the ph is high and reads no chlorine. What to do?

Salt generating systems cuase pH to rise over time so you generator appears to have been working. What is the salt level in the water? Perhaps your pool is low hence no more chlorine generation.

We change our pool that we have had for 10 years over to the intex salt system. 4ft X 24 ft round above ground pool. 13500 gla water. We put in 10- 40lb bas of pool salt and have ran the system for the 12...

The pool is green because you didn't take the metal out of the water first. It is too late now to do that ... you will just have to let the filter grab it. It may trake several days. Run the filter 24/7 for those couple days for best results.

Next time you fill your pool ... get a sequestering agent to grab the metals before you introduce CL to your pool. Use the sequestering agent according to the container instructions.

Your salt level should be around 3200 ppm, is it?

How much pool cholorine to put in a pool (15ft. by 4ft.)

There are a couple things going on here ...

You need to know how much warer is in the pool ...

Here are the formula:

Round Pool:
step one:
(diameter divided X 2 = radius)
Radius X Radius X 3.14 = surface area.
step 2: surface area X average depth X 7.5 = gallons in the pool.

step one:
Length X Width = surface area
step 2:
as above.

With this information, you can refer to your sanitiser container to answer your question.

There is more to this ... your pool water should be balanced to assure proper sanitation and economic operation. Your pH should be about 7.4, your Total alkalinity should be between 80 and 100 or 100 and 120 depending on the kind of chlorine you are using. If this is a vinyl pool you dont need to worry about calcium. Good CA level is 250.

To maintain proper CL level, you should test your water with a DPD kit. CL levels are affected by bather load, fill water and the sun. The sun consumes CL as does bather load.

Thanks for your question. I hope this helps.
