When will I see results after the treatment?
Usually, plants begin to show signs of weakness or die within 2 weeks. Signs include discoloration, elongation or wilting. Filamentous algae often turns pale yellow or whitish within 3 to 4 days. Planktonic Algae disappears in 24 to 48 hours. Dead plants with tough stems and sturdy root systems may remain standing until wind or waves break them up.
What happens to the dead plant material after the treatment?
Decaying plants and algae usually sink to the bottom after they die. Occasionally, plants with weak stems may break loose and float temporarily. Microscopic organisms in the water break down (decompose) plant materials leaving a fine residue of silt that settles to the bottom.
Will my water quality change after the treatment?
When large masses of vegetation decay, recycling of the plant materials occur. Some nutrients end up in sediment while others enter the water column. Some temporary decrease in dissolved oxygen levels may occur.
How long will control last?
Many weed species can be controlled for an entire season with a properly timed, single treatment. Herbicides do not kill seeds, and some do not get into root systems. This can result in a re-growth of plants requiring touch-up later in the season. Algae will generally require 3 to 6 weeks apart during the season because of their ability to reproduce rapidly.
Will I have fewer plants next year?
Once well established, nuisance plants will typically continue to be a problem each year. Some reduction in weed beds may occur the following year if treatments were made before seed production. Changes in dominant species or plant abundance is more likely to occur due to environmental factors such as water clarity, nutrient concentrations and weather factors. Different herbicides may be required.
Do resistant plants establish themselves?
There is some evidence that treating too often, year after year with the same chemicals, may result in the establishment of an unaffected species. This may require changing chemicals, dosage rates, using a combination of chemicals, or employing a combination of techniques (aeration, nutrient deactivation, dilution, etc.).
Phragmites beginning to take over shoreline areas around my pond and lake front property. What process is in place to deal with it?

What about swimming after an application? Can we eat the fish? What if my cat or dog drinks treated water? etc . . .
Are water gardens a mosquito breeding ground?
No, mosquitoes breed only in stagnant water. Installing a skimmer and Biofalls elminates stagnant water. The skimmer draws in the mosquito larvae from the surface of the water, drowning them.
Why should rocks and gravel be set throughout the pond?
Stones and gravel decrease maintenance, extend the life of the liner, stabilize the ponds walls, provide ballast against hydrostatic pressure, and looks more natural than a naked liner.
How high should the waterfall be?
Waterfall height will be determined by the elevation of the property on which the pond is installed. The waterfall should look as natural as possible. Waterfalls on flatland should only be about 2 ft. high. Higher waterfalls can be built on existing slopes, but make sure the pump can handle the extra height.
How many fish can I put in my pond?
Try to restrict fish quantities to a miximum on one 5 inch fish for every 5 square feet of surface area. (A 10 ft. x 10 ft. pond, for example could support 20 five-inch fish or 10 ten-inch fish).
At what temperature should I stop feeding my fish?
Once the water temperature drops below 50 degrees Fahrenheit, stop feeding your fish. During this time of year your fish will become dormant. Their respiration, metabolism, and overall activity slows down as they prepare for their winter hibernation. Feeding your fish this time of year can cause your fish to become sick and or even die.
Will raccoons eat my fish?
As long as your pond is at least two feet deep and eight feet wide with hiding places for the fish, they should be safe from raccoons.
Why should I put plants in my pond?
They take up nutrients in water that would otherwise be taken up by algae. Plants create an area for the fish to hide, cover surface area, provide food for fish, oxygenate the water, and soften the look of the rocks.
How do you determine the approximate gallons of water in a pond?
Gallons = length (ft.) x width (ft.) x average depth (ft.) x 7.48
