Rain Harvesting Solar Shield 300mm Tank Screen Algae Blocker with Flow Diffuser Fins | TASS24

Algae growth inside a rainwater tank is one of the most common and frustrating problems Australian homeowners face, and sunlight penetrating through the tank inlet is one of the leading causes. The Rain Harvesting Solar Shield 300mm tackles this issue at the source by blocking sunlight from entering through the tank screen opening. By cutting off the light that algae needs to thrive, the Solar Shield helps maintain cleaner, healthier water inside your tank without the need for chemical treatments or frequent manual cleaning.

What sets the Solar Shield apart from basic tank covers is its patented fin design. As inbound water passes through the fitting, the cleverly engineered fins distribute the flow evenly across a wider area, creating a gentle shower-like effect rather than a concentrated stream. This significantly reduces the force with which water enters the tank, minimising the disturbance of settled sediment at the bottom. The result is that your stored water stays clearer and cleaner between uses — a meaningful benefit for anyone relying on rainwater for household or garden use.

Installation is refreshingly simple. The Solar Shield is designed to sit underneath your existing tank screen, which means you retain full flexibility when it comes to positioning your inbound pipes. Unlike tank screen covers that require precise pipe alignment, the Solar Shield works with your current setup without demanding major adjustments. This makes it an ideal upgrade whether you are fitting out a new tank or improving an existing rainwater harvesting system.

Built specifically for Australian conditions and engineered with a patented design, the Rain Harvesting Solar Shield 300mm is a smart, low-maintenance addition to any rainwater tank. It addresses two common water quality challenges — algae growth and sediment stirring — in a single, easy-to-install fitting that works quietly in the background to protect your water supply.
