Swim Spa Chemical Guide

Guide for spas - Measurements are based on 6000 litres (Average Swim Spa)


Start up procedure

Step 1. Remove filters and fill spa through port that filters screw into until water is approximately half way up the Filter opening.

Step 2. Add Chemicals as per the below table:

Alkalinity Up


Spa Shock & Sanitizer

1 & ½ Cups (approx. 300 grams)

Shimmer & Shine

6 Capfuls



Daily Maintenance - After use

Step 1. Add Chemicals as per the below table:

Spa Shock & Sanitizer

3 – 4 Tablespoons (approx. 50 grams)




Step 1. Remove Filter Cartridges & Rinse Thoroughly

Step 2. Use test strip to check all chemical parameters

Step 3. Add Chemicals as per the below table:

Alkalinity Up

As indicated by Test Strip

Shock Right Plus

1 Tablespoon (approx. 15 grams)

Shimmer & Shine

4 Capfuls


If Alkalinity is High - remove 10% of water from spa and fill with tap water. Tap water is generally slightly acidic.  



Rinsing Filters

Remove filter and hose clean starting from top and working your way around and down to remove all dirt & contaminants.


Every 6-12 months

  • Empty Swim Spa and refill with fresh water
  • Start again with above start up procedure



  1. Hose out/clean filters every 1 - 2 weeks depending upon use.
  2. Leave spa cover off for 20 minutes whenever Spa Sanitiser or Spa Shock has been added to spa (only when safe i.e. no toddlers near spa area).
  3. Water must be changed at least every 6-12 months to avoid a buildup of chemical bi products.
  4. Always have the main filtering pump running whenever adding spa chemicals. Tip- Use water clean function on spa controller.
  5. The only bactericide in the whole system is chlorine. We do not recommend other types of chlorines such as peroxide or calcium based as they can cause problems with pumps and water clarity in a hot water spa.
  6. Do not over use spa shock as it can lower PH and cause your water to become acidic.
  7. New filters should be installed every 12 months.


Please use this information as a suggested guide, we recommend a full water test be conducted on your spa water by your local Pool & Spa Specialist Store.
