AstralPool CA Media Filter Range
Engineered for Crystal-Clear Water in Tough Australian Conditions
Made and tested in Australia, the AstralPool CA Media Filter range delivers sparkling, healthy pool water while withstanding our harsh UV, heat and salt-rich environments. Each tank is fully injection-moulded for maximum strength, then paired with AstralPool’s premium 6-way multi-port valve and 10-lateral under-drain to keep pressure loss ultra-low—even when you upgrade to energy-saving variable-speed pumps.
With four active models—CA280, CA300, CA340 and CA400—the CA range covers pools from small courtyard plunge pools right through to large family pools of ~190,000L. Simply match your turnover requirement (see table below) to pick the perfect model.
Built for Modern, Energy-Efficient Set-ups. The CA’s quick-lock ring and barrel-union ports make installation painless, and 40 mm or 50 mm connections integrate seamlessly with today’s variable-speed and inverter pumps. Pair with AstralPool’s Viron Active Glass for best-in-class micron filtration and noticeable sparkle.

Q1: Which CA model suits my pool size?
Match the litres your pool turns over in six hours to the “6 hr Turnover” column above. For example, a 75,000 L pool pairs perfectly with the CA280, while pools above 150 kL benefit from the CA400.
Q2: Can I run glass media instead of sand?
Absolutely. The CA range is optimised for both high-grade silica sand and recycled crushed glass. Glass offers finer filtration (down to 3 µm) and needs 20–25% less back-washing.
Q3: How often should I back-wash?
Under normal residential use, back-wash when the pressure gauge rises 8–10 kPa above the clean reading—typically every 4–6 weeks in peak season.
