The Problem

When the clean sandy bottom becomes covered in foul black organic muck this impedes fish spawning and desirable aquatic plants growth that is favored by clean sandy bottom. It creates a nutrient-rich rooting bed for invasive weeds that prefer to grow in this foul black muck.

As this mucky sediment accumulates and spreads, so do the invasive weeds.

So it’s not really invasive weeds so much as it is invasive muck that is the real problem.

Milfoil, lily pads, Wisconsin weeds water chestnut, are all surprisingly adept at exploiting creeping sediment accumulation and follow the sediment as it spreads and takes over the lake bottom.

The weeds die off in winter, fall to the bottom and decompose to form organic nutrient-rich muck again. So nutrient recycling creates invasive muck which nourishes invasive weeds.

New organics are added from agricultural runoff, wastewater and septic discharges, and leaves every fall so the depth of nutrient rich organics increases year after year.

How To Make It Worse

Understanding that invasive weeds can only invade where nutrient-rich muck accumulates again clarifies that the real problem is the recycling of nutrients as invasive weeds grow, die off, fall to the bottom and decompose to form nutrients again. It is obvious that the best way to make things worse is to promote nutrient recycling.

There are a number of ways to do this

» Herbicides

Herbicides quickly kill weeds so that the dead weeds fall to the bottom to decompose and perpetuate the nutrient recycling.

» Algaecides

Algaecides quickly kill algae so that the dead algae fall to the bottom to decompose and perpetuate the nutrient recycling.

» Chemical Treatments

Such as alum that clear the water and precipitate phosphorus down into the sediment to perpetuate nutrient recycling.

» Conventional Aeration

Conventional Aeration raises dissolved oxygen levels in the upper layers of the water column. Because phosphorus precipitates out of the water at higher dissolved oxygen levels acts in much the same way as chemical precipitants by recycling phosphorus back into the sediment.

The difference is that chemical precipitation tends to retain phosphorus in the sediment a little longer, whereas when conventional aeration fails to oxygenate the sediment phosphorus rapidly becomes dissolved in the water again.

How To Make It Better

In order to achieve this we:

Oxygenate the water column and sediment so that oxygen breathing organisms can proliferate and take up nutrients into the food chain.  No other technology has been shown to effectively achieve this.

Promote the natural digestion of the organics in the sediments to make them bioavailable for uptake into the food chain.  We use proprietary enzyme formulations to achieve this that are faster acting and more comprehensive in the range of organic sediments that they can digest than any other intervention on the market.

Deplete the nutrient stockpile after it is digested by providing micor-nutrient stimulants to promote the growth of organisms at the bottom of the food chain such as zooplankton that can ensure these nutrients are cleared through the Food Chain

In this way, muck and sediment can be digested and eliminated denying the invasive weeds the mucky nutrient rich rooting bed that they are dependent upon.
