Ammonia Block Marine eradicates poisonous ammonia infinitely quicker than any other product on the market. New aquariums can be stocked immediately without the fear of an ammonia spike or losing fish. Simply add the correct number of PODS to your canister filter and allow your filter to mature naturally over the next 12 weeks.
Each pack contains individually sealed 3 x 100g pods, sufficient for up to 800 litres of water.
1 POD - 0-200 Litres
2 PODs - 200-500 Litres
3 PODs - 500-800 Litres
For use in external canister filters and some large internal filters. Our PODs MUST be placed flat (not squashed up), to maximise exposure to water flow after the biological section to function correctly. When used with our Nitrate Remover, Ammonia Block must be placed before. This will ensure that you get clear and algae free water.
Remove PODs whilst using any fish disease treatment
In NEW or MATURE aquariums, it is recommended that you clean your filter before use
