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.

Do i need fresh water to change over to a salt pool

No the water does not to be changed, Just need to add salt. you can go to your local pool supply store for salt. Make sure you know how many gallons you have. You will need a system that converts your salt to cholorine. Good luck.

Our pool pump keeps shutting down

the pump is not functioning correctly, it should run constant, and is only controlled by the switch. are you by any chance running this pump off of an extension cord, because that can cause this symptom. an large draw such as a pump compounded by the voltage drop of the cord can cause the motor to overheat and shut down sporatically.

I am setting up my pool and it is 15 x 36.intex easy pool. Do I need to put any shock treatment or chemicals in the water. I heard you can pour in bleach?

yes i put pure bleach in my pool....I only use one bag of shock it about every month or so and i use 1 and half gallons of water each week. U can about tell when u will need to add it..when the water starts getting cloudy. My pool is a 20 round...8,800 gallons, so if u have a smaller pool for instance a 15 round.....5,000 gallons, i would only put maybe 3/4 of a gallon and a smaller pool about half a gallon of bleach per week.

Now how to put the bleach in the pool is what u need to focus on. The way i do it is where the water is returned to your pool i open the bleach and make sure u r wearing old clothing because i didnt once and i had bleach spots on my shirt due to the water splashing back up through the return. Well just pour slowly where the water comes back in the pool.....this is to prevent the liner from bleaching. So i suggest that u do it as slow as u can...its a lil but tidias when u pour it in compared to just dumping a bag of but its well worth the money u save. Pouring it over the water that returns to ur pool is to make sure it doesnt hit the liner and bleach it.....the water from the return will mix in with what u are pouring so that wont happen.....It will save alot of money...i dont use any other thing in my pool but bleach and shock it like i said about every cpl months and all the shock it is for is to settle everything to the bottom so i can vacuum it up. My pool is sparkling clear. i can see every lil spec. Good luck and I hope this helps.....Let me know!
God Bless

I just got a intex pool and it was given to me so I have no instructions. What all chemicals do I need to put in it and does the pump need to run while filling it up?

don't run the pump until the pool is full. You should buy some test strips and test the water . The strips will tell you what your low on. You will need chlorine for sure and probably some shock

I have an Intex 15' x 42" Easy Set pool. I bought chlorine tablets for it, and thought I could put them into the skimmer basket. Now I'm not so sure, and I can't get the DVD to play, and I've lost the...

Buy an inexpensive floater for in the water and put them in there. Putting them in the skimmer will just shorten the life of a pump that will already struggle to give you 3 years of service.
