Spa Pool Maintenance

Spa Pool start up and maintenance tips for lifelong relaxation

Buying a spa is the first step in a journey to lifelong relaxation. There’s nothing better than slipping into the warm water of your spa after a busy day or gruelling exercise. Starting up your spa properly using our tips for fresh water, chlorine and bromine spa pools and weekly maintenance will ensure you get maximum soaking satisfaction.

A weekly clean is essential spa care, but plan to drain your spa completely for a thorough clean every three-to-four months (or more often if you’re using it regularly or often have a lot of guests in it). A clean spa makes balancing the water chemistry – pH, alkalinity and sanitiser levels – easier. For personal comfort and health, and to protect your spa equipment, the objective is to have your water chemistry sitting within the following parameters:

  • Calcium hardness in the range of 150 – 300 parts per mission (ppm)
  • Total alkalinity in the range of 120 – 150ppm
  • A pH in the range of 7.2 – 7.4 being ideal.

Always add chemicals after you’ve used the spa. We recommend that chemicals be dissolved in a container of water and then tipped into the spa – add water to chemicals and not chemicals to water. Let the main jets run for 10 – 15 minutes after you’ve added chemicals to your spa’s water before you put the cover back on.

Fresh water spa pool start-up tips

If you’re using Auckland town supply water, we recommend following these start-up steps:

  1. Add 1 cup of calcium hardener with the filter running. Wait 10 minutes.
  2. Add 1 – 1.5 cups of pH buffer (sodium bicarbonate) with the filter running. Wait 10 minutes.
  3. Test pH and adjust as necessary using dessert spoon amounts of either pH increase or pH decrease with the filter running. Wait 10 minutes.
  4. Add 2 teaspoons of spa chlor or dichlor with the filter running. Wait 10 minutes.
  5. Ad 5 bromine tables to the floating dispenser in the spa pool.

Test the water balance (total alkalinity, pH and chlorine) each week and adjust when you need to. For example, if pH is high, add pH decrease, if pH is low add pH increase and if pH and total alkalinity are low add total alkalinity.

Fortnightly maintenance involves checking the cartridge filter is clean. If you need to clean it, give it a backwash and rinse. Check the pump basket for leaves and other debris.

Every 6 – 8 weeks we suggest changing the water (depending on how much use your spa has had). Clean the cartridge with cartridge cleaner like a pool and spa filter cleaner.
