For brown, or “tea-colored” water, we have Activated Pond Carbon. Brown water can be caused by leaves and other debris within the vicinity of the pond. Activated Pond Carbon is designed to clear the water from the extra nutrients that are introduced to the pond through the surrounding debris and conditions. For effective results, the carbon treatment should be changed about every 2 weeks.
There are many other factors that may be the cause to these water clarity issues. Temperature (Has the temperature fluctuated in your area lately?), the location of the pond (direct sunlight/shaded) and the surrounding environment (mulch, trees, plantlife, etc.). If you continue to experience problems with your water, please feel free to call one of your local retailers or contractors.
