AstralPool FG Fibreglass Media Filter Range
High-Performance Filtration for Australian Pools
The AstralPool FG Series is engineered for pool owners who demand robust performance and longevity in demanding conditions. Constructed with corrosion-resistant fibreglass and equipped with a top-mount multi-port valve, this filter series delivers outstanding clarity, minimal maintenance, and long service life in both residential and commercial applications.
Durable Build Meets Reliable Performance
Designed to meet the rigours of Australian summers, the FG series uses a seamless fibreglass-wound tank that resists UV, salt, and chemical degradation. The top-mounted multi-port valve ensures even distribution and simplified plumbing, making it ideal for tight equipment bays and straightforward retrofits.
With four active models—FG650, FG700B, FG800, and FG900—this range covers pools from small suburban installs to large family setups of up to 185,000L. Whether upgrading an older system or installing new equipment, the FG series balances flow, filtration speed, and media compatibility.
The FG filters accept various filtration media including silica sand and recycled glass (coarse and fine grades), allowing users to customise for water quality, flow efficiency, or eco-friendly operation.

Q1: Can the FG filter be retrofitted to older systems?
Yes, with its standard barrel-union ports and compact body, the FG series is ideal for retrofitting or replacing older filters with minimal plumbing changes.
Q2: Which media should I use—sand or glass?
Sand is cost-effective and reliable. Recycled glass (coarse and fine) offers finer filtration and longer back-wash intervals. Either works well with FG tanks.
Q3: How often do I need to back-wash?
Typically every 4–6 weeks under normal residential usage, or when pressure rises ~10 kPa above the baseline clean pressure.
