Rain Harvesting Solar Shield 400mm Tank Screen Algae Blocker with Flow Diffuser Fins | TASS25

Maintaining the quality of stored rainwater over time requires more than just a basic tank screen. Sunlight entering through the tank inlet creates the ideal conditions for algae to take hold, gradually degrading water quality and making ongoing maintenance a recurring headache. The Rain Harvesting Solar Shield 400mm addresses this directly by sitting beneath the tank screen and forming a reliable barrier against light penetration. With sunlight effectively blocked at the entry point, algae is denied the conditions it needs to grow — helping you preserve cleaner, better-quality water with minimal ongoing effort.

The Solar Shield’s patented fin design brings an additional layer of benefit that goes beyond simple light blocking. As rainwater flows in from your downpipe, the fins work to distribute and slow the incoming stream, transforming what would otherwise be a concentrated rush of water into a calm, even flow. This gentler entry significantly reduces the likelihood of disturbing the settled sediment layer at the bottom of your tank. For households relying on rainwater for drinking, cooking, or garden use, keeping that sediment undisturbed makes a noticeable difference to overall water clarity and quality.

One of the most practical aspects of the Solar Shield 400mm is how it integrates with your existing setup. Because it fits underneath the tank screen rather than replacing it, you retain full flexibility over where your inbound pipes are positioned. There is no need to reposition fittings or redesign your inlet configuration — simply install the Solar Shield beneath the screen and it gets to work straight away. This ease of fitment makes it equally suitable for new tank builds and upgrades to already-established rainwater systems.

Engineered for Australian rainwater harvesting conditions, the Rain Harvesting Solar Shield 400mm is a quiet but highly effective addition to any tank setup. By tackling both algae growth and sediment resuspension in one compact fitting, it helps ensure your stored water stays at its best season after season — without the need for chemical additives or complicated maintenance routines.
