How to Maintain Water Quality in Your Oasis Spa



To keep your water cleaning play you need to do four things:

Keep the PH at the correct level:

If you water has a low PH level, it will be acidic. While it will be crystal clear, it will be uncomfortable to relax in and can damage your equipment. High PH allows calcium to come out of the solution and make the water cloudy. For water clarity, your comfort and equipment life, make sure you keep your PH level between 7.4 and 7.6. Take the reading and if it’s outside of this range adjust it as directed on the bottle. Make sure to test the PH first as you’ll get false readings if you test after adding other chemicals. If necessary adjust the PH using Alkalinity Increaser or PH Decreaser.

Sanitise the Water:

Do this by adding an approved product as recommended by your Oasis Dealer. Make sure the filtration pump is running and add the correct dose to the middle of the spa. Make sure to keep the correct level of sanitizer in the water, and remember if you’re using the spa more frequently, you need to add more sanitizer. If you use it less you should back off the dosage.

Shock or Oxidize the water regularly to remove body oils, makeup, sun tan lotion and organic waste:

Failure to do this can make the water cloudy with oily bubbles on the surface. If you’re using the spa more, you’ll need to shock treat the water more often.

Ensure adequate filtration:

Filtration is essential to remove particles and organic materials from the water. It’s a good idea to add extra filtration after each use, by pushing the sanitize button on your Spa-Net SV control panel or push the Pump button on Spa-Tech ST control panels. Even more importantly, remember to keep your filters clean as body oils, makeup and sun tan lotion will clog the cartridges and make the water go bad very quickly. Dirty filters are also a breeding ground for bacteria that will make the water quality even worse.
