Winter Blend - Cold Water Liquid Clarifier & Sludge Reducer

UltraClear® Winter Blend is a natural cold-water pond clarifier and sludge reducer formulated to keep ponds balanced through fall and winter. 

When water temperatures drop below 55°F, most pond products stop working. Winter Blend Liquid is different. Its proprietary beneficial bacteria blend remains active down to 35°F, helping reduce organic buildup such as sludge, leaves, and fish waste that accumulate during colder months. 

This cold-water-activated formula sustains biological activity to support clarity and balance until spring. Use regularly to help minimize odors, support oxygen balance, and keep your pond in better condition year-round. 

Safe, eco-friendly, and non-toxic, UltraClear® Winter Blend contains no harsh chemicals. It’s completely safe for fish, aquatic plants, pets, and pond wildlife. Simply pour evenly across the pond for quick, even coverage — the easy choice for fall and winter pond care. 

• Cold-Water Optimized Formula: Proprietary blend of beneficial bacteria formulated to remain active in water temperatures as low as 35°F — when many pond products stop working. 
• Reduces Sludge & Organic Build-Up: Liquid formula helps minimize leaves, muck, fish waste, and other debris that collect through fall and winter. 
• Prepares Your Pond for Spring: Sustains biological activity during cold months, helping reduce buildup for an easier spring startup. 
• Safe and Natural: 100% biological and eco-friendly. Contains no harsh chemicals or hidden additives. Safe for fish, aquatic plants, pets, wildlife, and family enjoyment. 
• Supports Water Quality: Helps reduce unpleasant odors and contributes to a healthier, more balanced pond environment. 
• Simple Liquid Application: Just pour directly into your pond for quick, even coverage — ideal for larger ponds and ongoing seasonal care.
