Soon, the seasons will begin to change and the leaves will start to fall. At some point, your pond water will also begin to change, and you may notice it taking on a decidedly gross, brown color.
Today, Art of the Yard sheds light on reasons for dirty pond water. For the most part, there are actually two types of problems that will turn your pond water brown.
#1 Debris Tea
When pine needles and leaves fall into your pond water and are allowed to sit for a period of time, they begin to release tannins that turn the water an unappetizing shade of brown–exactly like tea does! The difference is that tea is delicious, and brown pond water is very undesirable.
#2 Sediment Stew
The second of the reasons for dirty pond water is similar to tea. In this situation, wet debris breaks down and ends up forming a mix of sediment on the bottom of your pond. This sediment can easily get stirred up by any fish you might have swimming around in your pond, even strong winds can disrupt the water.
Once these particles of sediment get caught up in your water pump, they’ll begin to circulate through the system, creating sediment stew and that unpleasant brown water.
Is it Stew or Tea?
The steps to find out the source of your brown water is simple. Simply fill a jar with pond water and let it sit for at least 24 hours without touching it or moving it. If when you come back, the water is still brown then you have yourself a nice jar of debris tea. Likewise, if you find that particles of sediment have settled to the bottom of the jar, then you have a case of sediment stew.
Proper Pond Cleaning
So, now that you’ve chosen between the two reasons for dirty pond water, you can go about getting it cleaned up. Whether you have debris tea or sediment stew, your first step will be to get out a pond vacuum or skimmer net and clean the bottom of your pond. You need to get the organics materials out of the water. Next, you can do a partial water change to help freshen things up. Just don’t forget to treat the water with a water conditioner if you have fish living in there!
If your problem was caused by sediment, then you can add good bacteria to the water to help eat up any organic debris and clear the water. If your problem was debris tea, throw a bag of activated carbon in the water to absorb the excess tannins and leave your water sparkling clean.
Of course, regular maintenance and cleaning out organic materials will keep your water perpetually clear, and you won’t have to worry about these reasons for dirty pond water.
