Pond Logic Activated Carbon Filter Pellets — 9 lb Bucket with Mesh Bag, Removes Tannins & Odors

Pond Logic Activated Carbon Filter Pellets clear tea-colored and stained pond water by adsorbing dissolved organics, chlorine, and odors while fitting conveniently into included mesh bags.

If your koi pond or water garden develops brown "tea" tinting from leaves, runoff, or decomposing plant matter, an effective adsorbent can restore visual clarity without disturbing fish or aquatic plants. Pond Logic's activated carbon pellets are designed to remove dissolved organics that cause discoloration and mild odors; each 9 lb bucket includes one mesh bag for straightforward placement in pond filters or flow-through housings. Routine replacement keeps filtration performance consistent and helps maintain aesthetic water quality between major maintenance sessions.

How does Pond Logic activated carbon improve pond clarity?

Activated carbon works by adsorbing dissolved organic molecules and tannins that stain water, not by mechanically trapping debris. When water passes through the carbon bed, discoloring compounds adhere to the carbon surface, reducing brown or tea-like hues and softening odors.

• Adsorbs tannins and dissolved organics that cause brown staining.
• Reduces mild odors from organic breakdown.
• Compatible with biological filter systems—doesn't disrupt beneficial bacteria when used as directed.

How do I use the pellets and mesh bag in a pond or waterfall filter?

Each 9 lb bucket contains pellets plus a fine mesh bag for easy installation. Place the filled mesh bag inside a filter chamber or near high-flow areas so water contacts the carbon; for trickle filters or canisters, position the bag where inflow is strongest for best adsorption.

• Apply 4–6 lbs of media per 1,000 gallons as a standard dose.
• For heavy staining, increase dosage temporarily to speed clearing.
• Replace media every 2–3 months or when water clarity or odor returns.

Will this product affect my koi, plants, or beneficial bacteria?

Pond Logic activated carbon targets dissolved organics and chlorine without chemically altering water parameters like pH or hardness. When used according to directions, it does not harm fish, aquatic plants, or established nitrifying bacteria that support pond health.

• Safe for koi and water garden plants when dosed properly.
• Does not release chemicals that change pH or mineral content.
• Replace periodically to avoid saturation and maintain filter performance.

How much should I buy and when should I change it?

Plan on 4–6 pounds per 1,000 gallons for routine maintenance; one 9 lb bucket treats a typical small-to-midsize pond for multiple months, depending on organic load. Replace spent carbon every 2–3 months or sooner if water clarity or odor returns; heavy leaf fall or storm runoff may require more frequent changes.

• Standard dosing: 4–6 lbs per 1,000 gallons.
• Expect 2–3 months of effective adsorption under normal conditions.
• Increase dose after heavy debris events for faster clearing.
