Step-by-Step Experts’ Guide to Pool Maintenance

Keeping a backyard pool sparkling isn’t about doing everything every day; it’s about doing the right things in the correct order. Use this practical, step-by-step routine from Pool Life to keep your water clear, safe and ready to swim year-round.

Pool Maintenance – Quick reference: target water levels

• Free Chlorine (FC): 1–3 ppm (salt: 2–4 ppm)
• pH: 7.2–7.6
• Total Alkalinity (TA): 80–120 ppm (fibreglass often 60–100 ppm)
• Calcium Hardness (CH): 200–400 ppm (fibreglass 100–250 ppm)
• Stabiliser/Cyanuric Acid (CYA): 20–50 ppm (salt pools often 60–70 ppm)
• Salt (for SWGs): Per manufacturer (commonly 3,000–4,500 ppm)

Ranges vary by surface, sanitiser, and manufacturer. If in doubt, ask Pool Life.

Your weekly step-by-step routine

Step 1: Clear the surface and baskets (5–10 min)

• Skim leaves and debris from the water surface.
• Empty skimmer and pump baskets.
• Check water level: keep it halfway up the skimmer opening.

Why it matters: Better circulation, less strain on the pump, and fewer nutrients for algae.

Step 2: Brush before you vacuum (5–10 min)

• Brush walls, steps, behind ladders, and along the waterline.
• Use the right brush for your surface (soft for fibreglass/vinyl; stiffer for concrete).

Why it matters: Brushing disrupts biofilm and algae, allowing filtration and chlorine to complete the job.

Step 3: Vacuum or run your cleaner (15–30+ min)

• Manually vacuum slowly (switching to waste or filter setting as needed) or run your robotic/suction cleaner.
• If your sand or DE filter pressure rises 8–10 psi above clean pressure, backwash.
• Cartridge filters: Rinse elements when the pressure reaches 8–10 psi or the flow slows.

Why it matters: Fine debris clouds water and drives up chlorine demand.

Step 4: Test the water (5–10 min)

• Use a quality test kit or digital meter to measure FC, pH, TA, CH, and CYA (and salt, if applicable).
• Note results in a log (paper or app). Trends help you identify and fix issues before they become apparent.

Pro tip: Test pH and chlorine levels 2–3 times per week in summer, and once a week in cooler months.

Step 5: Adjust in the correct order (10–20 min)

1. Total Alkalinity (buffer): Raise with buffer (sodium bicarbonate); lower by acid with aeration.
2. pH: Use pool acid to lower; soda ash to raise. Make changes in small doses, circulate 2–3 hours, retest.
3. Calcium Hardness: Add calcium chloride to raise the level. (Lowering requires partial drain/refill.)
4. Stabiliser (CYA): Add conditioner to protect chlorine from UV (don’t overshoot—hard to remove).
5. Sanitiser: Bring free chlorine into range. If FC is near zero or you’ve had heavy use/rain, shock.

Why this order? TA affects pH stability; pH affects sanitiser strength. Get the foundation right first.

Step 6: Set equipment to do the heavy lifting (2–5 min)

• Pump run time: Aim for 1–1.5 turnovers/day. As a quick rule, 6–8 hours in cool weather; 8–12+ in hot, sunny periods.
• Variable-speed pumps: Run longer on low rpm for clearer water and lower bills.
• Salt chlorinators (SWG): Clean the cell if it is scaled, and adjust the output to maintain FC within the desired range daily.
• Timers/automation: Schedule filtration after chemical additions for even mixing.

Step 7: Final checks and tidy-up (2–3 min)

• Confirm that the filter pressure returns to a “clean” baseline after backwash/clean.
• Rinse off tools, store chemicals in a cool, dry, ventilated area, and keep them out of reach of children and pets.
• Walk the pool area: check the gate self-closes/latches, look for trip hazards, and secure toys.

Daily, weekly, monthly & seasonal checklist

Daily (summer) / Every 2–3 days (cooler months)

• Quick skim of leaves
• Check the water level
• Spot-test pH and FC (especially after heavy use)

Weekly

• Full brush and vacuum/cleaner cycle
• Full test: FC, pH, TA, CH, CYA (and salt)
• Empty baskets; rinse cartridge (only if pressure indicates)
• Shock after big swim parties or storms

Monthly

• Deep-clean waterline tile/scum line
• Inspect cell (salt systems) and descale as needed
• Lubricate pump lid O-ring; check unions for weeping
• Verify timer programs with daylight-hour changes

Seasonally

• Pre-summer: Service equipment, check filter media/elements, confirm heater operation
• Pre-winter: Reduce run time and keep chemistry balanced.
• All year: Inspect fencing, CPR sign visibility, and lighting (use a licensed electrician for any electrical work)

Special situations (quick playbooks)

After heavy rain or dust storms

1. Skim and empty baskets.
2. Backwash/rinse or hose cartridges.
3. Test and correct pH and FC first.
4. If the water is dull, use a clarifier; if it is very dirty, use floc, then vacuum to waste.
5. Recheck salinity and CYA if you had significant dilution.

Cloudy water

• Check filter pressure and cleanliness, then pH (7.2–7.4) and FC.
• Brush vigorously; run pump longer.
• Correct the TA if pH drifts quickly.
• If there is no improvement within 24–48 hours, call Pool Life for a diagnostic.

Green water (algae)

1. Bring pH to ~7.2.
2. Shock to 10–20 ppm FC (depending on CYA).
3. Brush thoroughly (repeat daily).
4. Run pump 24/7 until clear; backwash/clean filter as pressure rises.
5. Consider using a phosphate remover if blooms recur, and verify that CYA is within range.

Stains

• Brown/orange that lifts with vitamin C = likely iron; black that lifts with chlorine tab = likely organic.
• Treat the cause (metal source, leaves sitting on the floor) first, then address the stain. Ask Pool Life for the correct remover.

Tools & products Pool Life recommends you keep on hand

• Leaf rake, wall/step brush (fit for your surface), telescopic pole
• Manual vacuum head & hose (even if you use a robot)
• Quality drop-test kit or reliable digital tester
• Spare skimmer/pump baskets and O-rings
• Filter cleaner, clarifier, floc (for emergencies)
• Acid, buffer (bicarb), soda ash, calcium chloride, stabiliser, liquid chlorine
• For salt pools: salt of correct grade; cell cleaning solution (as directed)

Save time (and money) with these habits

• Brush every week: It’s the cheapest “algaecide.”
• Log your tests/doses: You’ll spot patterns before problems appear.
• Dose small, retest often: Avoid overshooting pH or CYA.
• Run longer on low speed: Clearer water, lower power bills.
• Use a cover: Cuts debris, evaporation and chemical loss.
• Choose plants wisely: Low-litter landscaping near the pool reduces cleaning and phosphate load.
