Hot Tub Care Guide

Complete maintenance guide for keeping your hot tub in perfect condition

Daily Maintenance

Check Water Temperature

Ensure temperature is at desired level (typically 37–40°C). Adjust if necessary.

Skim Surface Debris

Remove leaves, insects, and floating debris with a skimmer net.

Keep Cover On When Not in Use

Reduces heat loss, keeps debris out, and improves safety.

Weekly Maintenance

Test Water Chemistry (2–3 times)

Use test strips or liquid kit to check:

  • pH: 7.2–7.6 (ideal 7.4)
  • Total Alkalinity: 80–120 ppm
  • Sanitiser: 3–5 ppm (chlorine) or 3–6 ppm (bromine)
  • Calcium Hardness: 150–250 ppm
Add Sanitiser

Maintain proper chlorine or bromine levels. Shock treat if needed.

Rinse Filter Cartridge

Remove and rinse with hose to remove debris. Rotate if you have spares.

Wipe Waterline

Remove oils and residue from waterline with spa cleaner.

Monthly Maintenance

Deep Clean Filters

Soak filter cartridges overnight in filter cleaning solution, rinse thoroughly.

Shock Treatment

Apply shock treatment to oxidise contaminants and restore clarity.

Clean Cover

Wash cover with spa cover cleaner and apply UV protectant.

Inspect Equipment

Check pumps, heater, jets for proper operation. Look for leaks.

Every 3–4 Months

Complete Water Change

Drain, clean, and refill your hot tub:

  1. Turn off power at breaker
  2. Drain using drain valve or submersible pump
  3. Clean shell with non-abrasive spa cleaner
  4. Flush pipes with cleaning product
  5. Refill with fresh water using hose filter if possible
  6. Balance water chemistry before use
Replace Filter Cartridges

Install new filters (or as needed if damaged/heavily stained).

Important Tips

  • Always shower before entering to reduce body oils and contaminants
  • Never mix different types of chemicals directly
  • Keep chemicals stored in a cool, dry place away from children
  • Run jets on high for 15–20 minutes after adding chemicals
  • Keep a maintenance log to track chemical additions and filter changes
  • Consider a professional service annually for deep maintenance

Common Issues & Solutions

Cloudy Water

Causes: Poor chemistry, dirty filters, insufficient sanitiser

Fix: Test and balance water, clean/replace filters, shock treat

Green Water

Causes: Algae growth from low sanitiser levels

Fix: Shock treat heavily, run filtration 24hrs, clean filters, may need to drain

Foam

Causes: Body oils, detergent residue, low calcium

Fix: Add anti-foam, shock treat, check calcium levels

Scale Buildup

Causes: High calcium, high pH, hard water

Fix: Balance pH, add scale prevention product, use water softener
