Benefits at a Glance
Restores silica levels to support beneficial diatom growth
Helps reduce recurring green water and nuisance algae
Improves water clarity naturally over time
Supports healthier oxygen conditions
Safe for fish, livestock, wildlife and pets
Why Silica Matters
Many waterbodies struggle with ongoing algae problems not only because nutrients are present, but because silica — an essential building block for beneficial diatoms — is lacking.
When silica is low, diatoms cannot thrive. Without strong diatom populations, nuisance algae gain the advantage and water clarity declines.
Diatomix IV restores bioavailable silica along with essential micronutrients, helping rebalance the system and support natural nutrient cycling.
How Diatomix IV Works
Diatoms are microscopic algae that:
Naturally absorb nitrogen and phosphorus
Require silica to build their cell walls
Help improve clarity and support aquatic food webs
Unlike nuisance algae, diatoms depend on silica.
By restoring this key element, Diatomix IV gives beneficial growth the conditions it needs to compete effectively.
As diatoms increase, they gradually reduce the nutrient fuel that supports unwanted algae blooms.
When to Choose Diatomix IV
Choose Diatomix IV if:
Your waterbody is regularly topped up with rainwater
Silica levels are likely low or depleted
Algae problems persist despite nutrient management
You are managing a larger pond, dam or reservoir
For standard systems without silica limitation, see Diatomix Concentrate or Garden Pond formulations.
How to Use
For best results:
Apply according to water volume and nutrient condition
Initial dosing may be higher than standard formulations due to silica requirements
Distribute evenly across the waterbody
