Wait a minute. I thought the idea was to get rid of nutrients in my pond. Why would I add trace minerals? Isn't that a nutrient?
To limit plant growth in the water column (algae, etc), the nutrients that are of most concern are the various forms of nitrogen (ammonia, nitrite, nitrate) and phosphorus.

The natural approach to pond management relies on bacteria to consume these nutrients; and in order for them to operate at peak efficiency they require minerals.

Many of the complex reactions that occur in nature will not happen without the required trace minerals being present.

This absence is a key reason that many ponds cannot breakdown nitrogen & phosphorus quickly/efficiently enough to prevent the over-growth of algae.

Providing the bacteria with the support that they need to thrive will accelerate the breakdown of these nutrients; thereby limiting the population of algae and alike.

Other helpful techniques include sufficient aeration (monitoring dissolved oxygen levels) and the addition of pond dye that inhibits UV rays, thereby preventing algae growth.

Why are trace minerals important to my lake or pond?
They improve the overall health & vitality of the beneficial bacteria that consume excess nutrients and clean the pond water. Read more in our blog: Why are trace minerals important to my lake or pond?

Where can I learn more about good pond management practices?
We recommend "The Efficient Pond Management Handbook" by Ryan McCaw.

This handbook is designed to give the average pond owner the knowledge and skills needed to manage the pond.

We like this book because it stresses a natural approach to pond management and a philosophy of solving the underlying problem rather than chasing symptoms.

How important is air/aeration/oxygen to maintaining a healthy, natural pond?
Good aeration is probably the single most important factor in water quality and the overall health of your pond. Read more in our blog: How important is aeration to maintaining a healthy, natural pond?
