The Astralpool Solo is the entry-level model in Fluidra Australia's new connected chlorinator range, and it replaces the outgoing E-Series and VX chlorinators. It is a straightforward salt chlorinator rather than an automation system, with filtration and compatible variable-speed pump control built into the same unit. The 18 gram per hour model is the smallest in the range, suiting pools to approximately 40,000 litres in tropical conditions and 50,000 litres in a temperate climate.

Chlorination

• 18 grams per hour output, adjustable
• Reverse-polarity self-cleaning cell with WWDG technology, cleaning approximately every 4 hours and adjustable to around 6
• Titanium electrode plates with ruthenium and iridium coating in a clear housing, so cell condition can be checked without pulling it out
• All Seasons operation reduces chlorine production as water temperature falls, when demand is lower
• Boost / Super Chlorinate mode for heavy bather loads, hot weather or contamination
• Spa Mode for smaller water volumes
• No-flow protection stops production if flow through the cell is not detected
• High and low salt warnings
• Designed around a recommended salinity of approximately 4,000 ppm

Filtration and Pump Control

• Filtration control built in, so pump and chlorination schedules run from the one controller rather than a separate timer
• Compatible variable-speed pump control. Confirm your pump before ordering - a full compatibility list has not been published, and universal third-party compatibility should not be assumed
• Compatible with Fluidra's Bluetooth filter-pressure sensor, which establishes a clean-filter baseline and flags when pressure has risen enough to warrant a clean or backwash

Control and Scheduling

• Touchscreen interface for output, timers, scheduling, pump configuration, modes, warnings and equipment status
• Illuminated ring on the fascia doubles as an equipment-status indicator, with different colours and patterns for filtering, chlorinating, updates, warnings and faults. Idle colour is customisable
• Built-in Wi-Fi and Bluetooth with mobile app control
• Four configurable seasons with adjustable start and finish dates. Schedules can be set by day of week and by season, so a Monday in winter runs differently to a Monday in summer without resetting timers as the weather turns

Replacing an E-Series or VX?

The Solo range replaces the outgoing Astralpool E-Series (E25, E35) and VX chlorinators. If your E-Series or VX unit has reached the end of its life, Solo is the current-generation equivalent.

If the cell is the only part that has failed, replacing the cell is usually the cheaper path, and genuine cells and electrodes for E-Series and VX chlorinators remain available. See our genuine Astralpool and Zodiac chlorinator cells and electrodes.

Solo or Echo?

Solo is the entry-level model: salt chlorination, filtration and pump control. It does not include heater control, pool-light control or dosing.

The Astralpool Echo is the mid-tier model. It adds control of one heater of any brand, pool lighting, and optional pH and ORP probes with automatic dosing. If you want heater control or dosing but do not need a full Halo system, Echo is generally the model to step up to. Full pool and spa automation sits with Halo Pro.
