NT Labs Koi Care Filter Bugs Liquid (250ml Treats 9100L)

【BACTERIA RICH LIQUID FORMULATION】: Filter Bugs is an easy-to use liquid formulation, containing a blend of Nitrosomonas, Nitrobacter, Nitrospira and supporting bacterial cultures. These bacteria will repopulate your filter with nitrifying organisms to ensure efficient biological filtration and perfect, stable water quality. 【POND FILTER BACTERIA】: Use Filter Bugs when establishing a new filter, at the beginning of the pond season in spring, or when ammonia or nitrite levels are elevated. 【ESSENTIAL FOR REGULAR POND MAINTENANCE】: Filter Bugs should be added immediately after a substantial water change or pond clean, at the beginning of the pond season, after using a medicinal treatment or adding new fish, and whenever there is a detectable concentration of ammonia or nitrite in the water. Filter Bugs can be added once per week, or more often if desired. 【EASY TO USE】: To work out the required dosage for your pond, simply calculate the volume of your pond in litres (length x width x depth (in cm)/1000) or alternatively, use our Online Dosage Calculator. Measure out the required amount of Filter Bugs and add directly to the biological media within the filter. Switch off UV filtration for at least 24 hours after adding Filter Bugs to allow the nitrifying bacteria to colonise the filter and the pond. 【USE WITH NT LABS HEALTH PROMOTING SALT】: Filter Bugs can be used when Pond Salt Plus is present in the water at ‘General Tonic’ and ‘Anti-stress’ levels.
