Duckweed and watermeal are floating weeds that reproduce VERY FAST! One week you have some growing along the edges of the pond, and the next, your whole pond is covered. Besides looking HORRIBLE, having the surface completely covered by weeds can lead to a fish kill.
These weeds usually re-appear in your pond in late spring to early summer. This isn't a mere coincidence. Duckweed and watermeal go dormant and drop to the pond bottom when the water temperature drops in the fall, and then re-emerges when the temperature rises! You HAVE to treat these weeds to manage them. They will not go away on their own.
Your standard aquatic herbicide alone usually won't kill these weeds. Creating a "chemical cocktail" that includes Algae Defense, Ultra Pondweed Defense, and Treatment Booster effectively controls these weeds. The ONLY TRICK is you need to kill ALL of the weeds. Leaving any living duckweed or watermeal will lead to regrowth. For 5,000 square feet Mix 32oz (1 qt) Ultra Pondweed Defense, 64 oz (2 qt) Algae Defense, 8 oz Treatment Booster, and 4 gal water. Spray directly on the weeds early of a sunny day.
It is very important to have pond aeration all the time, but ESPECIALLY when treating the pond with chemicals. As weeds die they consume oxygen from the water. Increasing oxygen levels will lower the risk of a fish kill during chemical application.
Make sure you know your pond size! Proper dosing is important. If you don't know your pond size- our experts can use our mapping software to determine the surface area of your pond.
How long will this treatment manage the weeds? This treatment will kill the current growth that you spray. If plants are left untreated they will repopulate. Also, these pesky weeds typically arrive in the pond via waterfowl. If there is a pond nearby with duckweed or watermeal, it is possible that they could be re-introduced. If any new growth is spotted, treat them immediately or remove them with a skimmer net before they have a change to multiply.
Note: Pond dye will not help control duckweed or watermeal as it does for algae or submerged weeds.

The use of copper sulfate to manage algae was once a common practice. Copper sulfate successfully killed algae in ponds. Although copper sulfate provided a successful short term solution for pond owners, the long term situation grew worse. Copper sulfate reacts quickly, leaving contact time to the day its applied. Copper settles to the bottom of the [...]
Many things add air to the water like waterfalls/streams, fountains, plants, wind, but is it enough? Tricky question!!In general, most large ponds are under aerated. This doesn't mean your fish are dying! Your fish can absolutely survive in your pond as is. Fish can live in very low oxygen environments. It is common that the [...]
Be sure to measure the ice thickness before each use! Turn off pond aeration systems or relocate diffusers to shallow areas that will not be used for on-ice activities. If the pond routinely has flowing water use extreme caution because flowing water can cause differential ice thickness and weak spots in the ice.Stay away from [...]
Well since we are water geeks here at Natural Waterscapes we thought we would share some fun water pics and facts from the recent and EPIC storm in the Sierra Nevada Mountains. First some advice: When your snow totals are measuring upwards of 10 feet, DO NOT ANSWER A KNOCK AT THE DOOR! Indoor skiing [...]
Don't overlook your pond this fall! A few simple actions in the Fall can reduce winter stress on fish and dramatically improve the spring conditions on the pond.

Why is aeration so important especially during the dog days of summer?As the summer heat rises and the number of daylight hours decreases it is critical to provide oxygen to ponds and lakes. Warm water holds MUCH less dissolved OxygenWarm water can not absorb as much oxygen as cold water so water temperatures above 70 [...]
