Pt 3 Above Ground Pools Chemical Types

  1. HOW MUCH STABLE CHLORINE IS REQUIRED? – The stabilizing effect does not take place at one with regular use of chlorinated cyanuric acid, unless a conditioner is used with the initial treatment. Without use of conditioner the dosage of stable chlorine will have to be increased to double the normal treatment for the first 3 or 4 weeks. Afterwards, the average pool will require a dosage of between 1 and 2 oz. per 10,000 gallons of water.

 

  1. HOW IS THE POOL CONDITIONED TO ELIMINATE THE STABILIZING WAITING PERIOD? – By adding 1 pound of conditioner (cyanuric acid) to the pool for every 3000 gallons a residual stabilizing concentration of 40 ppm will be established. This will normally achieve chlorine stabilization.

Pool Acid

  1. WHY DO I NEED TO USE ACID IN MY POOL? – The addition of some chlorine raises the pH since liquid (sodium hypochloride) tablet or granular (calcium hypochloride) are basically alkaline, continued use increases the pH above 7.6. to counteract this an acid must be used. Sodium bisulphate or muriatic acid will reduce the alkalinity.

  1. HOW MUCH ADIC DO I USE? – There are acid demand test kits available at your pool store that will tell you exactly how much acid is required at any one time. Be cautious when adding acid to prevent contact with tissue or clothing. Never put more than one pint of muriatic or 1 lb. of sodium bisulphate into a pool at one time. Wait four (4) hours and test pH before adding more acid.
  2. WHY DO I NEED TO USE SODA ASH IN MY POOL? – The pH at times may drop lower than 7.2 by adding too much acid or from the presence of some foreign material in the water. Use soda ash to raise pH to safe level.

Chemicals and My Filter

  1. DO I ADD CHEMICALS TO MY FILTER? – It is never advisable to add pool chemicals directly to your filter as it will damage your filter.

 

  1. HOW DO I ADD CHEMICALS TO THE POOL? – A predetermined amount should be selected and filter should be running. Caution. Protect your eyes, skin and clothing at all times. Do not mix different chemicals. Do not add different chemicals to pool at the same point.

  1. Liquid Chlorine – pour slowly into the water by walking around the pool. Place container as close to water as possible to avoid splashing.

 

  1. Dry Chlorine – Granular or Tablet – can be placed in a floating chlorine dispenser. Do not pour any un-dissolved powder into pool because this may cloud water, shorten filter cycle, or settle to bottom and stain the poor liner.

 

  1. Dry Stable Chlorine – Granular, powder or tablet should be placed in a floating dispenser

Chemical Types

  1. Muriatic Acid – Dilute acid 10 to 1 or 20 to 1 with water in a plastic bucket and slowly pour solution into water while walking around pool.
  2. Sodium Bisulphate – dissolve in a gallon of water (use plastic bucket) and slowly pour diluted liquid into water while walking around pool.
  3. Soda Ash – pre-dissolve soda ash in water and slowly add solution to pool water.
  4. wHEN IS THE BEST TIME FOR CHLORINATION? – In the evening after the sun has gone down and the day’s swimming is over. High temperatures and sunlight tend to dissipate chlorine rapidly.

  1. WHEN IS THE BEST TIME TO ADD ACID? – In the morning, however, one should test the water for chlorine residual and pH prior to the addition of any chemicals.
  2. WHEN SHOULD I TEST FOR CHLORINE RESIDUAL? – In the morning, before swimmers into the pool. If there were many swimmers in the the morning,  you should conduct an afternoon test to be sure the water is always properly chlorinated for healthful swimming.
  3. HOW DO I TEST FOR CHLORINE? – By using your pool test kit.  There are several kinds of test kits available from complex to simple. For most user a simple two stage test will suffice.

  1. WHAT IS SUPERCLORINATION? It is an when you use an increased does of Shock Chlorine  to handle bigger problems, to control these organisms and also to burn out other accumulation of organic matter. This type of treatment calls for from five to ten times the normal dosage of chlorine once every two or three weeks.

 

  1. COMBINED CHLORINE – Common Problem – When chlorine becomes combined there are some indications which often appear:

 

  1. A Strong test of chlorine (this is a reading of chlorine in an unusable from).

 

  1. A strong odor of chlorine (not found when chlorine and pH are in balance).

 

  1. Swimmers complain of eye irritation (this is not a normal reaction of a bather to chlorine).

 

  1. Water tends to be cloudy or grayish.
