Description
Target muck where it collects: on the pond bottom.
UltraClear Muck Digester Tabs sink through the water to help break down organic sludge, leaves, fish waste and other debris. A blend of nine beneficial bacteria strains and enzymes supports a cleaner pond bottom and helps reduce the odors associated with organic buildup.
Bottom-focused pond care
- Reach settled debris: sinking tablets deliver beneficial bacteria directly to the muck layer.
- Reduce organic buildup: helps digest leaves, fish waste and decomposing material.
- Treat problem areas: distribute around shorelines, coves and across the pond.
- Simple application: count the recommended tablets and toss them in; no premixing needed.
- Fish-friendly care: safe for fish, aquatic plants and wildlife when used as directed. Made in the USA.

Dosing by pond size
For ponds averaging 4 feet deep, distribute tablets evenly across the treatment area during the active season:
- 1/4 surface acre: 16 tabs (1 lb) per treatment.
- 1/2 surface acre: 32 tabs (2 lb) per treatment.
- 1 surface acre: 64 tabs (4 lb) per treatment.
Repeat every 2–4 weeks according to the label and pond conditions. For small decorative ponds under 1,000 gallons, use 6 tabs every 4 weeks, or every 2 weeks for problem ponds, following the package directions. For unusual depths or uncertain sizing, contact UltraClear for dosing help.
