This is a non-chemical approach which basically involves living organisms (microbes) feeding off of the excess nutrients that would otherwise be available for plant growth. Kleer's microbes are concentrated blend of naturally occurring bacteria and enzymes that rapidly biodegrade sludge, improve water quality, decrease suspended particulate matter and solids, and control odor if used correctly in the proper blend for the pond.
What is critical to the success of using this approach are a few basic guidelines:
Bacteria are living organisms and, if you use them in conjunction with herbicides there is a good chance they will prove to be marginally successful at best.
Dissolved oxygen levels must be at least 2 ppm for effective aerobic activity.
As the temperature drops, so does the effectiveness.
pH range of most products is 5.5 to 8.5.
Kleer and its packing are safe and nontoxic to humans and animals (including fish and other aquatic species).
Kleer comes in the box with:
1 packet of microbes
1 pack of dye (for additional charge)
No mixing required, just toss the packet in the water.
Just 1 pack treats 1/2 acre for up to 6 months.
It is important to note that in some cases, using Kleer could encourage the growth of filamentous algae. As the water clears up, more light will reach those filamentous at the bottom. (In this case, aquatic weeds and filamentous algae more or less play similar roles in the ecosystem) Knowing this, if the water quality has not deteriorated too much, then using Kleer early in the season will likely prevent the growth of filamentous algae all together.
