Aquarium - Filter Starter


Filter Starter 250ml

Suitable for coldwater & tropical aquariums, a live culture of filter bacteria to help breakdown fish waste

Filter Starter is a live culture of friendly bacteria for your filter. It contains Bacillus megaterium, B. pumilis, B. licheniformis, Paenbacillius polymyxa, Nitrosomonas spp., Nitrobacter spp., and Nitrospira spp. These becterial species help to breakdown fish waste and prevent the build up of toxic ammonia and nitrite.

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. To help prevent the build up of ammonia use NT Labs Ammonia Remover (Aquarium).

Always test your water using Aquarium Lab test kits.
