NT Labs Filter Bugs

NT Labs Filter Bugs

Biological pond treatment for filter support, sludge reduction and water balance

is designed to establish or replenish biological filtration in ponds. Ideal for new filters, the start of the pond season, or when ammonia or nitrite levels are elevated. This liquid formulation contains a blend of Nitrosomonas, Nitrobacter, Nitrospira, and supporting bacterial cultures to efficiently repopulate your filter and maintain stable water quality. Efficient Biological Filtration Ensures your filter quickly develops the bacteria needed for nitrification.

Biological treatments such as NT Labs Filter Bugs work best when the pond gives the bacteria the right conditions to establish. Use in chlorine-free water, maintain good oxygen levels and avoid dosing at the same time as strong chemical treatments unless the manufacturer says it is safe. They are especially useful after filter cleaning, new pond start-ups, medication courses, heavy feeding or seasonal waste build-up, where the biological system needs extra support.

NT Labs pond treatment guidance is built around treating the identified problem, not dosing blindly. NT Labs blanketweed products, for example, are positioned around water balance and remineralisation, while medicines should be matched to symptoms and water test results.

Biological support guidance

Use NT Labs Filter Bugs when the pond or filter needs biological support, such as after cleaning, new filter installation, medication, heavy feeding or seasonal waste build-up. Do not expect bacterial treatments to instantly remove years of sludge; they work by supporting natural breakdown over time, especially when oxygen levels and water temperature are suitable.

How to use safely

The product label should always take priority over general guidance. The points below are included to help customers use NT Labs Filter Bugs in a more careful and informed way.

• Use only in dechlorinated water; chlorine can reduce bacterial activity.
• Avoid dosing live bacteria at the same time as strong chemical medicines unless the label allows it.
• Maintain strong aeration so bacteria and filter media have enough oxygen.
• Allow time for biological products to work; sludge and waste will not disappear instantly.
• Reapply after medication, deep cleaning or large water changes where the label recommends it.
• Store the product as instructed and do not use if it has been damaged or contaminated.
