StoreTroubleshooting & MaintenanceWater BalanceLocation

Water Balance will directly affect the life of your swimming pool, interior surface, tile, stonework, and equipment. Maintaining Water Balance is the most important thing that you can do for your swimming pool.

Testing Your Water
  • You must test & balance your pool water a minimum of 2 times per week
  • You will need a test kit that tests for Total Alkalinity, pH, Free Chlorine, Total Chlorine, CYA (Conditioner or Stabilizer), and Total Hardness  
  • We also recommend that you log all test results by using the Insta-Link Home App on your Smartphone. This app can be found on the Apple Store or Google Play Store. This app will also provide you with instructions to what you need to add to your pool after entering your test results.

Procedure – 
  • Follow the directions on your test kit
  • Write down your readings for each test
  • Enter readings into the Insta-Link Home App (Open App, Click on Pencil)
  • Follow the directions on Insta-Link Home App for chemical additions and amounts

Frequency
  • Test Pool Water 2 Times per Week
  • Have a Professional Water Analysis Performed Every 90 Days (at your Local Leslie’s Pool Supply)
  • If you hire a Pool Service Company – we recommend having a Professional Water Analysis performed monthly to ensure the service company is properly treating your water.

Chemical Parameters (These are your targets for balanced water)
  • Total Alkalinity80-120 PPM
  • pH7.4-7.6 PPM
  • Hardness200-400 PPM
  • Free Chlorine2-4 PPM*Do not enter the pool if the Chlorine is above 4 PPM
  • Total Chlorine 2-4 PPM
  • Combine Chlorine0 PPM
  • Conditioner30 PPM
Note: Total Chlorine (minus) Free Chlorine = Combined Chlorine


Always adjust water chemistry in the following order:
  • Total Alkalinity 
  • pH
  • Hardness
  • Chlorine
  • Conditioner

Supplies to keep on hand
  • Muriatic Acid Lowers Total Alkalinity and pH
  • Baking Soda Raises Total Alkalinity
  • Soda Ash Raises pH
  • Granular Chlorine(Calcium Hypochlorite) Raises Chlorine
  • AlgaecidePrevents Algae
  • BueatecPrevents Stain, Scale, and Scum Buildup


Other Chemicals that will be needed periodically
  • Calcium ChlorideHardness Increaser
  • Cyanuric AcidIncreases UV Stabilizer

Warnings and Precautions

  • NEVER MIX CHEMICALS
  • NEVER ADD CHEMICALS ON TOP OF EACH OTHER
  • DO NOT INHALE FUMES FROM CHEMICALS
  • DO NOT SPILL CHEMICALS ON ANYTHING
  • ALWAYS FOLLOW LABEL INSTRUCTIONS ON CHEMICALS
  • ALWAYS ADD CHEMICALS TO WATER – NOT WATER TO CHEMICALS


Prolonged Water Balance Problems

Low Total Alkalinity will cause:
  • Etched Plaster
  • Corroded Metals
  • Stained Plaster
  • pH Creep, drift lower or bounce
  • Eye & skin irritation

High Total Alkalinity will cause
  • Scale Formation
  • Cloudy Water
  • Difficulty changing the pH or the pH will creep or drift up
  • Eye & Skin Irritation

Low pH will cause
  • Corrosive Water
  • Stains
  • Etched Plaster
  • Eye & Skin Irritation
  • Cloudy Water
  • Increased Chlorine Activity
  • Destruction of Total Alkalinity

High pH will cause
  • Scale Formation
  • Stains
  • Cloudy Water
  • Short Filter Runs
  • Eye & Skin Irritation
  • Decreased Pool Chlorine Efficiency

Low Calcium Hardness will cause
  • Difficulty Balancing Water
  • Etching of Plaster
  • Corrosion of Metal Components
  • Eye & Skin Irritation
  • Foaming

High Hardness will cause
  • Scale Formation on the vessel and in the equipment
  • Eye & Skin Irritation
  • Difficulty balancing water

Note: Water balance is a constant dance that is affected by a lot of factors - (rain, heat, humidity, fill water, organic material from bathers, etc.)
