Hydrogen Peroxide Instructions for Spas


Step 1: Clear the water

Water as supplied by the water authorities has chlorine included and so this needs to be eliminated if we are to have a chlorine free spa. Simply use SPA OXY SHOCK at the rate of 60 grams per 1000 litres of spa water and filter for 4 hours. This will oxidise the chlorine and any other unwanted matter in the water. Rain water and bore water also needs to be treated.

Step 2: Balance the water Using a water test kit or test strip.

Check the pH, alkalinity and calcium hardness levels of the water. The pH should be around 7.4 – 7.6 to be comfortable for people with sensitive skin. Total alkalinity should be between 80 – 120pp. If necessary, adjust these two levels using Alkalinity Increaser to increase the level or pH Decreaser to reduce them. Calcium levels that are lower than 100ppm can be damaging to equipment, as well as making it difficult to maintain pH levels and ultimately cause the water to go cloudy. Rain water is predictably low in calcium. Ideal levels for calcium hardness are between 100 and 200 ppm. To increase calcium levels use Hardness Raiser as per label directions.

Step 3: Sanitise the water

The water is now clear of contaminants and balanced and all that needs to be done is to sanitise the water with Spa Protector Sanitiser at the rate of one litre per 1000 litres of spa water. It’s that simple!

Weekly Maintenance - On a weekly basis we recommend that:

Step 1. The start up procedure is repeated although now we are simply treating the water to burn off any flacked skin, hair and other debris that has found its way into the spa. To do this use SPA OXY SHOCK at the rate of 30 grams per 1000 litres of spa water. Remember to run the filter for at least 4 hours BEFORE adding anything else.

Step 2. Should also be repeated. Human skin does tend to reduce the alkalinity level in the water. Calcium levels should not need adjustment once they settle.

Step 3. Is to check the levels of Hydrogen Peroxide in the spa using hydrogen peroxide test strips. The label instructions on the Hydrogen Peroxide are very explicit as to rates to add, however as a guide the average use (Average is 2-3 people using the spa 2-3 times per week for up to 30 minutes), would require a top up of 500 mls (2 measure jugs) of Hydrogen Peroxide per 1000 litres of spa water to keep the spa well sanitised. Please note that even if there has been no one in the spa it will still be necessary to add some Hydrogen Peroxide sanitiser because time and temperature will dissipate the levels.

Always Degrease the Pipes before Dumping Water.

Before dumping the spa remove filter cartridges, then add 20 mls per 1000 litres of spa water of Spa Conditioner and run the blower for 20-30 minutes to clean out the pipes. Always clean filter when water is dumped. Changing Water Completely empty the spa pool once the total dissolved solids (TDS) level exceeds 1000 ppm or every 6-8 weeks. Alternatively, replace 15% of the water every week. After refilling the Spa use Start up procedure to re-start the Spa

Replace the water any other time if:

The spa pool is used often by large numbers of people and it becomes difficult to maintain disinfectant level.
The water becomes cloudy and SPA OXY SHOCK does not clear up the water.
• If algae or slime appears to be happening
• If algae are present, dump water and scrub the inside of the spa with Spa Conditioner (wearing gloves) and rinse the spa before refilling.

Water Temperature.

Check the temperature regularly and maintain it at a suitable comfort level, usually from 28 degrees – 37 degrees C. Water temperature should certainly NOT exceed 40 degrees C.

A spa that is continuously heated will obviously use more Spa Protector Sanitiser.

When Not to Use the Pool or Spa

Spa pools should NOT be used:

• If the sanitiser level and or pH is not within recommended levels and the water is dirty or cloudy

• If the filtration unit or pumps are not operating correctly

• By persons who are under the influence of drugs or alcohol

• By person with open wounds or who feel unwell or are pregnant

• By persons who are immuno compromised.

General rules for enjoying a spa

• Always keep your head above water

• Spend NO LONGER than 20 minutes in the spa at any one time

• Always supervise children using the spa.
