Pool Maintenance for Beginners: Keep Your Pool Crystal Clear

The Three Pillars of Pool Care

Pool maintenance comes down to three things: circulation, chemistry, and cleaning. Get these right and your pool will stay clear and safe all year.

1. Circulation

Your pump and filter are the heart of your pool system.

How Long to Run Your Pump

• Summer: 8-10 hours per day
• Winter: 4-6 hours per day
• Run during off-peak electricity hours to save money
• Variable speed pumps can run longer at lower speeds (more efficient)

Filter Types

• Sand filter — Backwash every 2-4 weeks, replace sand every 5-7 years
• Cartridge filter — Hose off monthly, replace cartridge every 1-2 years
• DE (diatomaceous earth) — Best filtration but most maintenance

2. Water Chemistry

Test your water weekly with a test kit or strips.

Key Levels

Parameter	Ideal Range
pH	7.2 - 7.6
Free Chlorine	1 - 3 ppm
Total Alkalinity	80 - 120 ppm
Calcium Hardness	200 - 400 ppm
Cyanuric Acid (stabiliser)	30 - 50 ppm

Adjusting Chemistry

• pH too high — Add hydrochloric acid (muriatic acid)
• pH too low — Add sodium carbonate (soda ash)
• Low chlorine — Add liquid chlorine or granular shock
• Green water — Super-chlorinate (shock) and run filter 24 hours

Salt Chlorinators

If you have a salt pool:

• Maintain salt level at 3,000-5,000 ppm (check manufacturer specs)
• Clean salt cell every 3-6 months with diluted acid
• Still need to monitor pH and alkalinity manually

3. Cleaning

Weekly Tasks

• Skim leaves and debris from surface
• Empty skimmer baskets
• Brush walls and steps (prevents algae)
• Vacuum floor (manual or robotic cleaner)
• Check and empty pump basket

Monthly Tasks

• Backwash or clean filter
• Test and adjust calcium hardness and stabiliser
• Inspect equipment for leaks or unusual noises
• Clean waterline tile with pool-safe cleaner

Seasonal Tasks

• Start of summer — Full chemical balance, check equipment, clean filter
• End of summer — Reduce pump hours, balance chemistry for lower usage
• Winter — Consider a pool cover, reduce chemical dosing

Common Problems

Green Pool

1. Test and adjust pH to 7.2
2. Super-chlorinate (triple the normal dose)
3. Run filter 24-48 hours continuously
4. Brush walls and vacuum dead algae
5. Backwash filter after clearing

Cloudy Water

• Usually caused by poor filtration or unbalanced chemistry
• Check filter is clean and running long enough
• Test and balance pH and chlorine
• Add clarifier if chemistry is correct

When to Call a Professional

• Persistent green or cloudy water despite treatment
• Equipment failures (pump, filter, heater)
• Cracked or damaged pool surface
• Leak detection
• Annual equipment service and safety inspection
