Getting Started: The Perfect Setup

Before you fire up the jets, you need a solid foundation. Here’s how to nail the basics.

Filling Your Spa

  • Choose a clean water source. Tap water is fine—just let it stand for an hour.
  • Remove any covers and filters. Fill to the manufacturer’s recommended level.
  • Inspect shells or acrylic surfaces for dust and debris. A quick wipe with a microfiber cloth helps.

Initial Chemical Dose

When fresh water hits the spa, it’s thirsty for sanitiser. Aim for:
Chlorine: 3–5 ppm (parts per million)
Bromine: 4–6 ppm

Use granules. They dissolve fast. Add 60 g of chlorine granules per 1 500 L of water. Wait for levels to stabilise before your first dip. It sets the stage for balanced water and avoids surprises later.

Water Chemistry 101: Balance Like a Pro

Many spas falter because owners skip chemistry. Not you.

Test Daily

Grab test strips. Dip, wait 15 seconds, compare. You’ll get:
pH: Should sit at 7.2–7.6
Total Alkalinity (TA): 80–120 ppm
Hardness (TH): 150–250 ppm

Testing daily builds intuition. You’ll know how your usage, rain or refill affects chemistry.

Adjusting pH and Alkalinity

  • Low pH (acidic): Add a pH increaser (sodium carbonate).
  • High pH (alkaline): Pre-dissolve pH minus (sodium bisulphate), pour into deepest part.
  • Low TA: Use a TA booster.
  • High TA: Partially drain and refill, or use a specialist pH-reducing product.

Proper balance protects pumps, heaters and your skin. Too acidic, and metal parts corrode. Too alkaline, and scale builds up. Nobody wants spotty shell surfaces.

Filter & Circulation: Keep It Flowing

Your filters are the spa’s lungs. Clean lungs = happy spa.

Cartridge Care

Most acrylic spas use cartridge filters. Here’s your weekly routine:
1. Turn off the spa.
2. Remove the cartridge.
3. Hose off debris at a 45° angle.
4. Soak overnight in a filter cleaner if it’s heavily soiled.
5. Rinse and replace.

Dirty filters strain the pump and foul water. If your spa is busy—with kids, tanning sessions or poolside parties—check filters twice a week.

Pump and Jet Check

  • Listen for unusual noise.
  • Feel for consistent flow from jets.
  • Inspect seals and hoses for leaks.

A tiny drip today can be a flood tomorrow. A quick check saves repair bills.

Cleaning & Foam Control: Say Goodbye to Scum

Even with perfect chemistry, surface grime happens. Here’s how to stay on top.

Surface Cleaning

Once a week:
– Wipe waterline with a spa-safe surface cleaner.
– Use a soft cloth. Avoid kitchen sprays—chemical residues can cause foam.

Tackling Foam

Foam comes from lotions, soaps or detergents on swimwear. To nip it:
– Encourage a quick rinse (costume on).
– Add a defoamer product if bubbles appear.

Simple routines keep water glassy and inviting.

Seasonal Care & Winterising

Seasons change. Your spa routine should too.

  • In winter, run jets daily for 15 minutes to prevent freezing.
  • Use an insulated cover and thermal blanket.
  • If you close your spa, drain completely, clean piping with a pipe cleaner, and leave plugs off to ventilate.

A little prep keeps your tub ready to rock when spring arrives.
