Active aquarium management, also active algae management. Clearing the water of nutrients by installing a stable growth rate able to support the system. This is done by using a refuge and active feeding. for example a growth rate of 1ppm No3-N daily is installed by active balanced feeding. if the system accumulates nutrients the feeding is adjusted. This way growth is able to clear the water of nutrients at all times. Growth can be anything, heterotrophic, autotrophic, as long it can be harvested. I do prefer to use producers, macro-algae, because a lot of information is available. This way one is able to start up a marine system and condition the system to the desired nutrient export rate before the first consumer is added.@Belgian Anthias Can you explain this "AAM" process you so often reference without linking us to another article? Thanks.
