Maintaining Correct Alkalinity

• Alkalinity should be between 90-140 ppm (parts per million).
• If Alkalinity is high than weekly additions of acid should be added.
• If Alkalinity is low than soda ash also known as alkalinity up should be added in doses of 1kg and check.
• Add more if nescessary.

Maintaining Correct PH

• When PH is correct the system works best.
• PH should always be between 7.6-7.8 for pools other than fibreglass which is 7-7.2.
• A higher PH means that you will not utilise the full potential of the system and more chlorine is required.

Total Dissolved Solids (TDS)

• This indicates mineral content in your water.
• The TDS should be around 1000ppm.
• This creates a medium to conduct current and is beneficial in keeping ozone levels at maximum.
• TDS levels can be raised by adding Sodium chloride (salt) or water softener salt.
• Ordinary city water has a typical TDS of about 400-800ppm, while some well water with high Calcium content could run over 1,200ppm.

Metals

• Borehole and well water should be checked before filling your pool.
• The Dolphin releases very small amounts of copper.
• Correct Metal levels are between 0.5-1.0.
• Copper levels should be checked once every 8 months and should not exceed 1ppm.
• If levels are higher disconnect unit at switch (on side of unit) and retest.
• Reconnect unit when levels are at 0.5

Green Algae

• This is the easiest form of algae to control and the most common type.
• Usually this algae accumulates around the edge of a pool.
• Unfortunatelly without the system you will have to use large amounts of algaecide.
• With the system it should dissapear within 2 weeks.

Black Algae

• Black Algae is one of the most difficult algaes to control.
• This algae is like a fungus and can develop quite quickly if not treated on time.
• Large amounts of algaecide are required as well as high levels of chlorine.
• You can eradicate it by sprinkling small amounts of chlorine powder over it at night when the pump is off.

Maintaining Adequate Chlorine Levels

• Chlorine levels should always be kept at 1ppm with your system.
• Check and maintain this level especially after it has rained heavily.
• Without the system your levels must be maintained at 3ppm.
• The best way to add chlorine is through the weir don't sprinkle.

Filtration

• Your filter should always be properly maintained.
• Make sure your sand is not brittle.
• Your sand should be replaced every 4-5years.
• If you have bought a new house and are not sure it is better to replace the sand.
• Brittle sand will cause damage to your pump and motor.

Backwashing and Rinsing Your Pool

• Backwash and then rinse your pool once a week.
• Check to see the water passing out is clear.

Pump Run Time

• Set your timer to run for 9hrs daily with the system.
• Without the system you will be running your pump for 12hrs daily.
