UltraClear Cold Water Muck & Sludge Remover

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.  Dosing Instructions Pond Size (Gallons) Dosage Amount Frequency 500 gal (≈0.004 ac) 15 pellets (≈0.15 cup) Weekly until surface freezes 1,000 gal (≈0.01 ac) 30 pellets (≈0.3 cup) Weekly until surface freezes 10,000 gal (≈0.08 ac) 300 pellets (≈3 cups) Every 2 weeks until surface freezes 20,000 gal (≈0.15 ac) 600 pellets (≈6 cups) Every 2 weeks until surface freezes 40,000 gal (≈0.30 ac) 1,200 pellets (≈12 cups) Every 2 weeks until surface freezes 160,000 gal (≈1 ac) 4,800 pellets (≈48 cups) Every 2 weeks until surface freezes When to Use Use in early fall to break down leaves and organic debris before winter.
