Diatomix IV 1 Litre

Diatomix IV – Advanced Silica-Enhanced Water Health Solution for Low-Silica Systems

Diatomix IV is specifically formulated for waterbodies where silica levels are low, where the water is regularly recirculated or where rain water is used for topping up the pond.  Silica is essential in the water for good diatom health, to reduce persistent and unwanted algae blooms. Diatomix IV supercharges diatom growth — the natural nutrient cyclers — so nitrogen and phosphorus are locked up naturally, improving water clarity, dissolved oxygen and ecosystem balance. Ideal for larger ponds, dams, reservoirs and irrigation storages.

Benefits at a glance:

• Corrects silica deficiency to support beneficial diatom growth
• Reduces nuisance algae and improves clarity
• Enhances oxygen levels and stabilises aquatic ecosystems
• Safe for fish, livestock, wildlife and pets

Why Silica Matters

Many waterbodies suffer from chronic algae issues not because of excess nutrients alone, but because they lack bioavailable silica — the key nutrient diatoms require to thrive. Without silica, diatoms can’t outcompete harmful algae, even when nitrogen and phosphorus are high.

Diatomix IV delivers silica and essential micronutrients where they’re most needed, tipping the balance back to natural nutrient cycling.

How Diatomix IV Works

• Diatoms are microscopic algae that naturally absorb nitrogen and phosphorus.
• They require silica to build their cell walls — other algae do not.
• Diatomix IV supplies bioavailable silica and micronutrients so diatoms flourish.
• As they grow, they remove nutrient fuel from the water that would otherwise feed nuisance algae.

How to Use

For best results:

• Apply Diatomix IV according to water volume and condition.
• Typical initial dosing is higher than standard formulations due to silica limitations and larger body volumes.
• Spread applications across the waterbody for even coverage.
• Contact us for exact dosing guidance or use our dosing calculator.

Available in 1 Litre and 5 Litre bottles and is best for larger ponds, dams or reservoirs where there is low silica and the dose rate is higher.
