A:  Brown water can destroy a beautiful landscape.

That tea-colored water is typically caused by one of two things: tannins being released by dead leaves, similar to what happens when you steep your chamomile tea; or an optical illusion caused by reflected decomposing pond debris. The two causes have two different solutions. Here’s what we recommend.

Inspect Water

First, take a closer look at the water. Dip a clear glass in the water and hold it up to the light. If the water looks discolored, you’ve got tannin tea; if it’s clear, you’re dealing with a mucky pond.

Clearing Tannin Tea

Carbon is your solution for clearing brown water. Pond Logic® Activated Carbon comes with a fine-mesh bag, which holds the carbon pellets when they’re submerged. It’s easy to use:

  1. Pour the recommended amount of pellets into the bag. A 500-gallon pond, for example, requires 2 to 3 pounds while a 1,000-gallon pond requires 4 to 6 pounds.
  2. Place the bag in a high water-flow area, like your skimmer or waterfall, so as much water as possible flows through the carbon.
  3. Wait for the carbon to do its job! Once the discoloration has disappeared, you can remove the carbon and discard it.

Cleaning Up the Muck

If you have a mucky pond, natural beneficial bacteria and some elbow grease will make your water sparkle again.

  1. Pond Logic® Season Defense®, which works well in cooler fall weather, contains microorganisms that help break down the muck and accumulated debris at the bottom of your pond.
  2. Giving your pond a good old-fashioned cleaning can help, too. Removing the muck and decomposing organics with a pond vacuum or net will give those bacteria a chance to focus on breaking down the small stuff.

  1. Carbon only treats the symptom. You need to clean the pond regardless.
