Autumn Prep - Natural Cold Water Clarifier & Sludge Reducer

UltraClear® Autumn Prep Tablets are a natural cold-water pond clarifier and sludge reducer designed to keep ponds balanced through fall and winter. 

When water temperatures drop below 55°F, most pond bacteria products stop working. Autumn Prep is different. Its proprietary probiotic blend remains active all the way down to 32°F, helping reduce organic buildup such as sludge, muck, fish waste, and leaves when other products go dormant. 

• Cold-Water Optimized Formula: Proprietary blend of beneficial bacteria designed to remain active in water temperatures as low as 32°F — continues working when many other pond products stop. 
• Reduces Sludge & Organic Build-Up: Concentrated tablets help reduce the accumulation of muck, fish waste, and leaves at the pond bottom, supporting improved clarity and depth. 
• Seasonal Prep Made Simple: Helps minimize heavy organic buildup during colder months, making spring startup faster and easier. 
• 100% Natural & Eco-Friendly: Made from a proprietary mix of beneficial bacteria and enzymes. No harsh chemicals, no hidden additives. Completely safe for fish, pets, aquatic plants, and family enjoyment. 
• Supports Water Quality & Reduces Odors: Autumn Prep helps balance oxygen levels and minimize unpleasant pond odors, while contributing to a healthier aquatic ecosystem.
