Product Information
Full details
Oase AquaActiv SediFree is designed for pond owners looking to eliminate unsightly sludge and foul-smelling deposits from their water features. Its key benefit is a two-component oxidation and biological degradation process that restores biological balance and improves water clarity by breaking down organic matter at the source. The primary caveat is that it requires a minimum water temperature of 12°C to function effectively, making it unsuitable for winter use.

FAQs
Can I use SediFree in the winter?
No, the product is most effective at water temperatures of 12°C or higher and will not perform well in cold winter conditions.
Do I really need to turn off my UVC?
Yes, UVC radiation kills the beneficial bacteria included in the SediFree formula. Leaving it off for three days is essential for the product to function.
Is SediFree safe for fish and plants?
Yes, SediFree is designed to be safe for a pond's ecosystem when applied according to the recommended dosages.
How often should I use the maintenance dose?
You can apply a maintenance dose of 10 to 20ml per 1,000 litres whenever you notice an accumulation of sediment returning.
Does it remove all sludge instantly?
No, SediFree is a biological treatment that requires time to oxidize and mineralize sludge through bacterial action.
Troubleshooting
No visible reduction in sludge after application
Check that the water temperature is above 12°C and ensure the UVC was turned off for the required three-day period.
Water remains cloudy despite treatment
Allow additional time for the bacteria to mineralize the debris; ensure proper pond aeration to support bacterial activity.
Pros and Cons
Pros
- Efficiently reduces sludge and foul odors
- Uses natural biological mineralization processes
- Easy to apply directly to affected areas
- Helps prevent the formation of fermentation gases
Cons
- Only works effectively at water temperatures above 12°C
- Requires disabling UVC clarifiers for three days post-treatment
- Not intended for instant results; requires time for bacteria to act
Setup, Compatibility & Care
To ensure optimal results, follow these preparation steps:
- Check Temperature: Ensure the water temperature is at least 12°C.
- Preparation: Calculate your pond volume to determine the correct dosage.
- Application: Evenly scatter the required amount of granulate over the pond surface, focusing on areas where sludge has accumulated.
- UVC Management: Switch off your UVC equipment for a full three days immediately after application. This prevents the UVC light from killing the active bacteria before they have a chance to colonize the sludge.
- Maintenance: Monitor water clarity and repeat with maintenance doses if the sludge buildup begins to return.
