Product Details
✓BREAKS DOWN SLUDGE ALL SEASON LONG: Fish waste, fallen leaves, uneaten food and dead plant matter settle and turn to muck. Live beneficial bacteria and enzymes break down that organic sediment, reducing muck by up to 1 inch per month when used as directed, so foul odors fade and your pond keeps its depth. Results vary with pond size, temperature and organic load.
✓1 OZ TREATS UP TO 1,000 GALLONS: Follow the dosage chart: 1/2 oz for ponds up to 500 gal, 1 oz up to 1,000, 2 oz up to 2,000, 3 oz up to 3,000, 6 oz up to 6,000 and 10 oz up to 10,000 gallons. This 32 oz bottle holds 32 doses for a 1,000-gallon pond, under $1 per dose.
✓POUR IT IN. IT GOES EVERYWHERE: Shake well and pour directly into the pond. The liquid spreads through the whole water column, into coves, shelves and the pond floor, with no tablets to place and no mixing. It won't tint your water or stain rocks and liners, so your pond looks clear while it works.
✓SAFE FOR KOI, PLANTS, PETS & PEOPLE: 100% biological, made with non-pathogenic bacteria and no harsh chemicals or dyes. Safe for koi, goldfish, aquatic plants, pets, birds and wildlife, and safe to swim in, even while dosing. Made in the USA by UltraClear, clarifying ponds since 1993.
✓3 SIMPLE USES: Spring Start: begin dosing when your pond becomes active. Regular Maintenance: dose monthly, or up to once a week for best results. Fall Clean-Up: dose daily for 4 to 7 days to break down waste before winter, then switch to UltraClear Cold Water Complete or Cold Water Muck Remover. Turn off UV sterilizers for 24 hours after dosing.
