It may seem strange to be talking about Winter fish stress while temperatures are still mild. However, now is the time to take action if you manage an aging pond or lake. As organic debris accumulates over years, it becomes more and more important to consider taking action to reduce biological oxygen demand and the build up of toxic gas in the water column.
Simple accumulation of leaf debris and fish waste can trigger a Winter fish kill. Fortunately there are easy steps that will minimize the risk and result in a healthier water body and fish population year-round.
- Install and operate an aeration system. A bottom aerator is the most efficient mechanism to ensure that the entire pond is well oxygenated.
- Add beneficial bacterial such as Pond Clear and Muck Remover. These targeted strains of beneficial bacteria digest nutrients in the water column and organic debris on the bottom (including recently fallen leaves and dying vegetation). As the bacteria go to work, they convert the organic muck and vegetation to harmless gasses that are released to the atmosphere. This process is most effective while water temperatures are above 38 degrees Fahrenheit.
- Limit the amount of leaves and other organic debris that enters the pond or skim the surface to remove floating debris before it sinks.

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 [...]
