Resin Products Ammonia Block removes harmful ammonia quicker than other products on the market.

It removes all ammonia and ammonium from aquariums within 4 hours. New aquariums can be fully stocked once set up without the fear of an ammonia spike or losing fish.

Ammonia Block is perfect for ensuring there are no ammonia spikes during the early development of new filters. Use after the biological stage of filtration and that will ensure that the bacteria has no problems populating the filter media since it will always have enough food.

Remove the Ammonia Block pod(s) after 12 weeks - you will not need to add more since the filter will now be mature.
However, if you are going on holiday and relying on other people to feed the fish it is very useful to add Ammonia Block pod(s) to the filter to ensure that there are no pollution incidents (from over feeding) while you are away.

Resin Products Ammonia Block uses a unique premium-grade ammonia selective ion-exchange resin to quickly remove ammonia from aquarium water - this product can be used in both freshwater and marine aquariums.
