Rain Harvesting Solar Shield 500mm Tank Screen Algae Blocker with Flow Diffuser Fins | TASS26

For larger rainwater tanks fitted with a 500mm tank screen, managing water quality over time is a priority that deserves a purpose-built solution. Sunlight passing through the tank inlet creates the perfect environment for algae to develop, and once established, algae can be difficult and time-consuming to deal with. The Rain Harvesting Solar Shield 500mm is engineered to eliminate this problem before it starts. By sitting beneath your tank screen and cutting off the light at the entry point, it removes the core condition that algae depends on — keeping your stored water cleaner and your maintenance routine simpler.

Beyond its light-blocking capability, the Solar Shield 500mm features a patented fin design that transforms the way water enters your tank. Rather than allowing inbound rainwater to rush in as a single concentrated stream, the fins spread and soften the flow, producing a shower-like effect that is far gentler on the water already sitting inside the tank. This means the sediment that naturally settles at the bottom of your tank is far less likely to be disturbed and stirred back up into your water supply. For households using rainwater for drinking, cooking, or irrigation, this protection of water clarity is a genuine everyday advantage.

A key practical benefit of the Solar Shield is that it installs beneath your existing tank screen rather than replacing it. This distinction matters because it means your inbound pipe positioning does not need to change — you keep full flexibility over where your inlet pipes connect, something that tank screen covers do not always allow. Whether you are building a new rainwater system from scratch or looking to improve the performance of an existing setup, the Solar Shield 500mm slips into place with minimal disruption and gets to work immediately.

Designed with Australian rainwater harvesting conditions in mind, the Rain Harvesting Solar Shield 500mm delivers reliable, long-term protection against two of the most common water quality issues — algae growth and sediment resuspension — in a single, low-maintenance fitting. It is a smart investment for any Australian homeowner who wants to get the best possible quality from their rainwater storage, year after year.
