What chemicals are needed for a new swimming pool

Answers:

Swimming pool chemicals

Most folks will only need one chemical to start a new pool: Chlorine. Most common is "tri-chlor" which contains both chlorine and stabilizer.
Next, you will probably need some chlorine "shock". This is unstabilized chlorine that is used in relatively high doses to completely sanitize your water and eliminate bound chlorine.
Also, get a decent chemical test kit (a DPD one not an OTO) and some test strips. Use the test strips to do quick checks and the DPD test kit to actually measure the levels.
Over time you'll probably also need some pH up and/or down to adjust the pH.
Eventually, you'll need algaecide (everyone does!). But wait until you need it to buy it.
That should get you started.  

Answer

The previous response assumes that the pool water has already been balanced. If you are filling the pool with water yourself and not having a pool maintenance firm do it, then you'll likely need to add Calcium (via Calcium Chloride or possibly Calcium Carbonate if you need to increase alkalinity as well). This assumes that your source water has less than 300 ppm CaCO3 equivalent of calcium hardness.
You'll also need to add bicarbonate of soda to get the Total Alkalinity to 80-120 ppm. After that, then it's mostly just adding chlorine and adjusting pH (with acid if you use liquid chlorine; base if you use Tri-Chlor).
Be aware that if you use Tri-Chlor (or Di-Chlor), you will be increasing your Cyanuric Acid (CYA) levels substantially over even one summer of use. If you do frequent backwash of your sand or DE pool filter (paper filters don't need backwash) and if you splash out lots of water, then the CYA level might be OK. Otherwise, 1 tablet of Tri-Chlor produces (in 16,000 gallons) about 2.5 ppm of chlorine AND 2 ppm of CYA. Di-chlor produces 1.5 times as much CYA for the same amount of chlorine as Tri-Chlor.  

Answer

Chlorine and acid are the only things you will need. Trichlor is never a good idea. It contains stabilizer and will lockup your chlorine so it will not oxidize. You would be better off buying cyanuric seperately and adding it by handl. At least you will be able to control the amount of cyanuric. Only 10 to 20 is recommended.
Humm, in the above answer - is that 10 - 20 pounds or parts per million =PPM?






Having a properly balanced pool is not difficult, but it does take work.

I'm the pool operator at our local YMCA and keeping an 80,000 gallon pool balanced is pretty easy, once you all the elements in place and know what you're doing.

Chlorine 1.5-3.5, alkalinity 80-100, pH 7.6-7.8, not 7.2, hardness 150-250, not up to 400.

You have to stay on top of it because the chlorine can go down in a matter of hours if no one properly checks it.





Answer***

You'll need calcium, Sodium Bicarb., muriatic acid, chlorine, chlorine tabs and a floater (don't put your tabs in the skimmer) and a good Taylor DPD Test Kit. You'll also need to know how to make adjustments and the meaning of each reading. Check out the link below for more info.
ANSWER- Here is a step by step answer
Firstly work out how much water your pool holds using this formula
(1 cubic metre = 1000 Litres or 4.5 Litres per 1 Gallon)
Then Adjust your Ph Levels To a:
Minimum of 7.2
Optimum of 7.4
Maximum of 7.6
so 10g per 1000 litres per day of Ph plus or minus until you get a reading of 7.4
Then Adjust Algaecide levels
25ml per 1000 litres for initial dose then 2ml per 1000 litres every 2 weeks.
Then Adjust Chlorine levels
Initial Dose of chlorine is 6Grams per 1 Cubic Metre
Then 1.8g of Chlorine per 1 cubic metre when needed
Always have your filter pump in operation when adding chemicals to your pool and keep it running for at least half an hour afterwards.

Never Mix Chemicals!!!
Do not allow anyone in the pool for at least half an hour after treatment.
Please test chemical levels before letting anyone enter the pool.
To insure high water quality you should be running your filter pump for an optimum of between 2 and 4 hours a day. Filter use will increase when used with an intex cover or solar cover, as air cannot circulate.
Wow that is some great information very help full thanks
