Aquarius Technologies: How to fix a green pool 

A green pool is every pool manager’s nightmare. It’s not just unsightly—it’s a sign of algae growth, poor water balance, and ineffective sanitisation. The good news? With the Australian made, Aquarius ULTIMA Automatic Pool Controller, you can turn that murky mess back into sparkling blue water—without the stress of manual guesswork.

Why does a pool turn green?
Green water usually means:

• Low chlorine levels – algae thrive when sanitisation drops.
• Poor circulation – stagnant water allows algae to bloom.
• Imbalanced pH – high pH makes chlorine less effective.

The ULTIMA controller tackles all these issues automatically, giving you real-time monitoring and precise chemical dosing.

Step 1: Diagnose and monitor
ULTIMA’s smart sensors continuously track chlorine, pH, and ORP levels.  If one or more of these parameters go out of range, you’ll know exactly what’s wrong — no more relying on guesswork.

Step 2: Shock the pool
Activate Shock Mode on the ULTIMA:

• It calculates the correct chlorine dose based on your current readings.
• Manual Mode allows you to chlorinate the pool for a customised period.
• These rapid boost options provide the ability to kill algae and restore sanitisation quickly.

Step 3: Improve circulation
Green pools often suffer from poor water movement. The ULTIMA can:

• Extend Chlorination run times automatically during recovery.
• Integrate with variable-speed pumps for efficient circulation.

Step 4: Balance pH and alkalinity
Algae love high pH. The ULTIMA:

• Monitors pH continuously.
• Doses acid and or CO2 automatically to keep levels in the ideal range (7.2–7.6).

Step 5: Prevent future problems
Once your pool is clear:

• Keep ULTIMA FAC in Flow Mode for ongoing monitoring and control.
• Schedule regular chlorination and filtration cycles.
• Enable Aquarius Aquareporter remote alerts via SMS or email for early warnings of imbalance.

Bonus tip
For stubborn algae, add an automated timed algaecide dose through the ULTIMA’s chemical feed integration. You can even monitor and control everything remotely via the ULTIMA Aquareporter online app.

Why ULTIMA?
Unlike manual methods, the Aquarius ULTIMA automates the entire process—saving time, reducing chemical costs, and ensuring crystal-clear water all season long.
