UltraClear Biological Clarifier - Natural Pond Clarifier with Beneficial Bacteria

Q: What does UltraClear Biological Pond Clarifier do?

It uses natural, beneficial bacteria to break down organic waste, sludge, and excess nutrients that cause cloudy water, foul odors, and algae growth—keeping your pond clear and balanced without harsh chemicals.

Q: Is UltraClear Biological Pond Clarifier safe for fish and plants?

Yes. It’s 100% biological and non-toxic, making it completely safe for fish, plants, wildlife, and pets when used as directed.

Q: How often should I apply the product?

For best results, dose weekly during the warm months when water temperature is above 50°F. In heavily loaded ponds, you may use it twice-weekly until clarity improves.

Q: Can I use it with UV clarifiers or algaecides?

Yes, but for maximum bacterial effectiveness, turn off your UV clarifier for 24–48 hours after each UltraClear treatment. Avoid using chemical algaecides simultaneously, as they can reduce bacterial activity.

Q: How long does it take to see results?

You’ll typically notice improved clarity and reduced sludge within 1 day, with the full results visible in 7–14 days of consistent use, depending on pond size, temperature, and nutrient levels.

Q: What’s the difference between UltraClear Biological Pond Clarifier and UltraClear Muck Digester Tabs?

The Pond Clarifier treats the entire water column for overall clarity and nutrient reduction, while Muck Digester Tabs target bottom sludge directly. Many pond owners use both for best results.

Q: Can I use this in my koi pond or decorative water feature?

Absolutely. UltraClear is ideal for koi ponds, ornamental water gardens, fountains, and any natural or lined pond system.

Q: How and how often should I dose UltraClear Biological Pond Clarifier?

Dosing depends on your pond size and condition. Reference the dosing chart on the product label, or the product detail page. We recommend 1 oz per 2,500 gallons applied weekly. For Spring Prep, we recommend a daily maintenance dose applied for 3 consecutive days. For problem ponds, apply 2–3 times per week until the issue resolves.

Q: How do I apply UltraClear Biological Clarifier?

Shake well, dilute the measured dose with ~2–3 gallons of water and pour evenly around the perimeter of the pond to ensure good distribution.

Description

UltraClear® Biological Clarifier is a natural pond clarifier powered by beneficial bacteria and enzymes to improve clarity and balance without harsh chemicals.

When suspended particles and organic debris cause hazy or murky water, Biological Clarifier helps reduce the buildup that clouds your pond. Unlike chemical flocculants that provide only temporary particle clumping, this biological formula supports long-term clarity while contributing to a healthier pond ecosystem.

Perfect for spring start-up, routine pond maintenance, or addressing seasonal cloudiness, Biological Clarifier is easy to apply — just pour evenly across your pond. Safe, natural, and eco-friendly, it helps maintain a clear, balanced, and thriving pond environment year-round.
