Before and After Treatment of water with Diaotmix
Using Diatomix to remove filamentous algae in a pond

How to Use & How Much?

We recommend for garden ponds up to 10 square metres (e.g. 5 metres long and 2 metres wide) put 8 mL – yes only 1 teaspoon of Diatomix, in your pond three times a week. This is just $1.65 per week.

To ensure better coverage in your pond it is best to mix the recommended dose of Diatomix in a container with some pond water, then throw scoopfuls of this across your pond. Avoid getting it on top of any weeds as it needs to be in the pond water.

A Natural and Safe Way to Restore Pond Balance

Algae problems return because nutrients remain in the water. Killing algae doesn’t remove the cause — it only treats the symptom.

Diatomix works differently. It supports beneficial natural algae that compete for nutrients, helping your pond stabilise over time rather than crash and rebound.

With regular use, most garden ponds show visible improvement within a few weeks.

For Garden Ponds, treatment starts around $1.65 per week!

Simple weekly dosing is all that’s required to maintain clear, healthy water.

Safe for fish, pets and plants. Simple weekly dosing. Visible improvement within weeks.

From $1.65/week to keep your pond clear

Choose the Right Diatomix for Your Pond.

Garden ponds vary in size and nutrient load. Choosing the right Diatomix formulation ensures effective, long-term algae control without harsh chemicals.

Most small garden ponds (under 10 m²) use our Garden Pond formula.

Hi, I was so skeptical about putting in such a small amount of the liquid you sent us into the dam, but holy cow in 4 weeks it’s the best looking dam in our street. It’s astounding the transformation, we just love it.You guys are geniuses and we thank you so much for the awesome productKind regards, Liz

We contacted AlgaEnviro due to concerns with the health of our two small dams. There was minimal apparent water borne life visible and both the wild ducks and our dog that once swam in the dams, no longer did so. My wife had read about Diatomix in the local newspaper and we purchased their product, using it pretty much according to AlgaEnviro’s directions. After a month or so, water borne life and water clarity began improving and now several months later the dam water is very clear, water borne life abounds and both the dog and ducks are back swimming in the dams.

Our pond is fed by runoff, mainly from paddocks, and is frequented by wild life such as ducks. Consequently, we have struggled with the effects of algal growth and blooms. Since the volume of water ranges up to 500㎥ and the existence of sensitive wild life such as eels preclude the use of chemical solutions or the use of barley grasses/extracts, we sought a means of keeping the pond algae free. We have achieved some limited success by building swales and planting gross feeding plants. When we learned of Diatomix, we trialled the product and found the effect to be better than we imagined. Within months, the water has cleared substantially and the quality is significantly improved.

The team at AlgaEnviro are a wealth of knowledge and were really helpful so we could optimise the use of Diatomix within our pond setting. Since using Diatomix we have noticed a significant decrease in the growth of filamentous algae. Previously I was unblocking the pump on a near daily basis however now with an established population of diatoms I havent had to unblock the pump in the past eighteen months.

Our Council Park Pond is going really well. In summary, the Azolla disappeared within a week or two (except on the bank above the waterline. I don’t know if I am seeing things because I want too, but there seems an abundance of life in the water, I have observed carp, turtles, small fish in schools (about 4cm long) and lots of water insects. Local kids fishing say there are goldfish and redfin too.
