Essential Pool Chemicals

Understanding the four main categories of pool chemicals and their specific purposes

Sanitizers & Pool Shock

Chlorine-Based Pool Shock

  • Cal Hypo: Fast-acting, unstabilized chlorine
  • Di-Chlor: Stabilized with cyanuric acid for sun protection

Chlorine-Free Pool Shock

Potassium Monopersulfate: Oxidizer that prevents chloramines from forming

Water Balancers

pH & Alkalinity Adjusters

  • Sodium Bicarbonate: Raises alkalinity (baking soda)
  • Sodium Carbonate: Raises pH (soda ash)
  • Muriatic Acid: Lowers pH and alkalinity

Hardness & Chlorine

  • Calcium Chloride: Increases calcium hardness
  • Chlorine Neutralizers: Reduces excessive chlorine

Algae Control

Prevention & Treatment

  • Phosphate Removers: Eliminate algae food sources
  • Algaecides: Prevent algae growth on surfaces

Algae makes surfaces slippery and can harbor dangerous bacteria like E. coli

Specialty Cleaners

Maintenance Products

  • Filter Cleaners: Remove oil, grime, and obstructions
  • Tile Cleaners: Maintain surface appearance
  • Vinyl Cleaners: Preserve liner integrity

How to Test Pool Water

Three proven methods to accurately measure your pool's chemical levels

Test Strips

Quick & Easy Method

Measure pH, alkalinity, chlorine, and specialty tests like salt or TDS levels.

1Hold strip underwater for 2-3 seconds
2Remove with padded side facing up
3Wait 15 seconds without shaking
4Compare colors to package chart

Test Kits

Precise Liquid Testing

Color-changing reagents provide accurate measurements of water chemistry.

1Collect water from 18" below surface
2Fill test vials per kit instructions
3Add correct amount of reagent
4Compare sample colors to chart

Digital Testers

Electronic Convenience

Smartphone-connected devices offer detailed readings and convenience.

Smartphone integration
Detailed digital readings
Higher cost, variable accuracy

7-Step Water Balancing Process

Follow this proven sequence to achieve perfect water chemistry balance

1Adjust Alkalinity

Target: 80-120 PPM

Alkalinity acts as a pH buffer. Low alkalinity leads to corrosion and unsafe swimming conditions.

  • Raise: Add sodium bicarbonate
  • Lower: Add muriatic acid

2Adjust pH Level

Target: 7.2-7.6

Prevents surface damage, cloudy water, and skin irritation.

  • Raise: Add soda ash
  • Lower: Add muriatic acid

3Calcium Hardness

Target: 200-300 PPM

Prevents equipment corrosion and surface etching.

  • Raise: Add calcium chloride
  • Lower: Drain & refill partially

4Sanitize Water

Target: 1-3 PPM Chlorine

Use chlorine tablets, liquid chlorine, or salt generator.

  • Chlorine tablets
  • Liquid/powder chlorine
  • Salt chlorine generator

5CYA & TDS Levels

CYA: 35-60 PPM
TDS: Under 1,500 PPM

CYA protects chlorine from UV rays. High TDS requires water replacement.

6Shock Pool

Weekly or bi-weekly shocking destroys bacteria, algae, and chloramines.

Shock after heavy use, storms, or algae presence

Step 7: Test and Verify

Retest all levels to ensure everything is within proper ranges. Repeat adjustments as needed.

Frequently Asked Questions

How often should I test my pool water?

Test your pool water 2-3 times per week during swimming season, and at least once per week during off-season. After heavy use, storms, or when adding chemicals, test before and after to ensure proper levels.

What happens if my pH is too high or too low?

High pH (above 7.8) causes cloudy water, skin irritation, and reduces chlorine effectiveness. Low pH (below 7.0) causes equipment corrosion, surface etching, and skin/eye irritation. Maintain pH between 7.2-7.6 for optimal comfort and equipment protection.

Can I use household chemicals in my pool?

While some household products like baking soda can be used for alkalinity adjustment, always use pool-specific chemicals when possible. They're formulated for pool conditions and won't introduce unwanted additives that could affect water balance or equipment.

How long should I wait to swim after adding chemicals?

Wait times vary by chemical: pH adjusters (20 minutes), chlorine (20-30 minutes), shock treatment (8-24 hours depending on type), algaecide (15-30 minutes). Always test water to ensure levels are within safe ranges before swimming.

Why is my chlorine disappearing so quickly?

Rapid chlorine loss can be caused by high bather loads, algae growth, insufficient CYA levels (chlorine burns off in sunlight), or contamination. Check CYA levels, shock the pool to eliminate chloramines, and consider increasing sanitizer levels during heavy use periods.
