If left, fish waste will build up and become toxic. Filter Starter contains Bacillus megaterium, B. pumilis, B. licheniformis, Paenbacillius polymyxa, Nitrosomonas spp., Nitrobacter spp., and Nitrospira spp. These friendly filter bacteria break down fish waste, making the water safe for fish. Add to a new aquarium to help ‘kick-start’ the filter, when adding new fish, after a filter clean/water change, or after using a disease treatment. How to use? Calculate the volume of your aquarium in litres (Length x Width x Depth (in cm)/1,000). Alternatively, use our Dosage Calculator to help you. Shake the bottle thoroughly before use. Bacteria starts working immediately, improving the performance of the filter. Repeat dose weekly for 4 weeks when starting a new aquarium or a single dose after each water change.
