Aqua-Guard Pool Opening Kit - Up to 40,000 L

Day 1: After the pool water has circulated for a minimum of 8 hours:

Add Meta-sol from our Aqua-Guard Pool Opening Kit according to the instructions on the label. Meta-sol will tie-up and inactivate any stain causing minerals that may be present in the water. It is especially important to do this step prior to pH adjustments in case your pool water is acidic. Continue to circulate the pool water overnight.

Day 2:
1) In the morning, with the water continuing to circulate, broadcast 1kg of Oxy-Out across the surface of the water. This oxidizing product destroys organic wastes that have accumulated over the winter, without bleaching surfaces.

2) One hour later, adjust Total Alkalinity and pH if required. Depending on the amount of adjustment required to balance the water chemistry, this process may take anywhere from 2-8 hours. Try our Aqua-Guard Test Strips.

3) A half hour after the last Alkalinity and pH adjustment, Shock the pool with Soft Shock, a gentle chlorine shock treatment that will eliminate organic wastes and debris that have accumulated in the water during the winter. Add 1 pouch of Soft Shock per 50,000L of pool water by broadcasting it across the pool surface. 

Alternately, if your pool water is green or cloudy upon opening, a stronger chlorine shock like our HTH Supershock, may be required at this time.

Day 3: In the morning (or a minimum of 12 hours after shocking the pool), add the Concentrated Aqua-Guard Algaecide as per bottle directions to kill potential algae spores as well as prevent the growth of new ones during the start-up process.  If your pool required a stronger chlorine shock and the chlorine level is still high, it is recommended to wait 24 hours before adding the algaecide.

Once the opening kit has been added and your pool water is clear, you are now ready to begin your maintenance program.
