CrystalClear SludgeShock Beneficial Microbe Balls — Open-Box, 5% Off

A simple application provides effective muck reduction, enhances pond clarity, improves overall balance, and helps combat sludge issues.

SludgeShock breaks down muck and debris in ponds from fish waste and decaying plants, targeting buildup at the pond floor and hardscapes.

For optimal performance, SludgeShock is most effective when both components—the SludgeShock balls and the enzyme-rich liquid—are used together.

SludgeShock effectively treats up to 2,500 gallons of water in water gardens and koi ponds. For optimal results, it should be reapplied every 4 weeks.

For effective treatment, SludgeShock should be evenly distributed throughout the pond to ensure that all areas benefit from the active ingredients.

CrystalClear SludgeShock is an excellent choice for koi ponds, water gardens, and a wide range of backyard water features. It provides pond owners with an easy and effective solution to combat persistent bottom debris and organic buildup by specifically targeting the sludge and settled waste that accumulates over time. Applying SludgeShock is straightforward—simply pour the live beneficial microbe balls and the enzyme-rich liquid directly into the pond, eliminating any complicated steps. For those seeking even more comprehensive pond care, this product can be used in conjunction with the PondShock pond clarifier ball. While PondShock works throughout the water column to break down suspended debris and clarify water, SludgeShock focuses on the pond floor and hardscapes, where heavy muck and organic waste tend to gather. SludgeShock is specially formulated to tackle the stubborn muck and debris that builds up in ponds over time. Its powerful blend of beneficial microbes and enzymes effectively breaks down waste generated from fish, decaying plant material, excess nutrients, and other organic sources. By targeting these compacted layers of sludge at their source, SludgeShock helps restore a clean pond floor, reduce odors, and promote a more balanced ecosystem. The effectiveness of natural SludgeShock begins the moment it enters the water. The concentrated blend of beneficial microbes and enzymes immediately sinks to the bottom, seeking out and breaking down organic waste while targeting the sludge that settles on the pond floor, rocks, and other hardscape surfaces. For optimal results, it is recommended to use SludgeShock when water temperatures are above 50°F.
