The Importance of NT Labs Filter Bugs
Every healthy pond relies on the nitrogen cycle to process fish waste. Without the correct bacteria, fish waste (ammonia) becomes toxic, stressing your fish and potentially causing fatality. NT Labs Filter Bugs jump-starts this process. The solution contains high concentrations of Nitrosomonas and Nitrobacter bacteria. These are the two groups of organisms that convert harmful ammonia into nitrite, and then finally into safer nitrate. Furthermore, you should use this biological solution after any major event that might compromise your biological filter. This includes cleaning the filter media, performing large water changes, or completing a strong chemical treatment.
How to Establish a New Filter Fast
When setting up a brand new pond or filter system, you need NT Labs Filter Bugs to inoculate the media quickly. A new filter lacks the necessary bacteria to handle fish waste, leading to the highly toxic “new pond syndrome.” The application is simple: shake the bottle well, measure the dose, and pour the solution directly over the filter media. Next, ensure your UV sterilizer is switched off for 48 hours following application. This prevents the UV light from killing the new bacteria before they colonize the media. This product drastically reduces the time required to safely stock your pond. It ensures that your water quality remains stable during this critical startup period.
Maintain Your Pond’s Balance
Even in mature, established ponds, beneficial bacteria can suffer die-offs due to seasonal changes, temperature drops, or the use of specific pond treatments. Regularly dosing with the filter bugs solution acts as a preventative maintenance measure. It reinforces the existing biological colony. By boosting the concentration of these filter bugs, you improve the overall efficiency of your biological filtration. This results in less sludge, clearer water, and a more stable environment for your koi. Additionally, choose the appropriate size—the 1 Litre container is highly economical for larger, routine maintenance.
