Complete ammonia-oxidizing Nitrospira and ammonia-oxidizing archaea as biological supplements for freshwater aquaria

Alexander K Umbach, Owen Ikert, Benoit Choquet, Josh David Neufeld

This study evaluates the effectiveness of nitrifying supplements containing Nitrospira and ammonia-oxidizing archaea in freshwater aquaria, showing they reduce ammonia and nitrite more effectively than conventional supplements.

Fish load impacts biofilter microbial communities and nitrifier populations during establishment of freshwater home aquaria

Alexander K Umbach, Natasha Szabolcs, Laura A. Sauder, Josh David Neufeld

This study shows that varying fish loads in freshwater aquaria affect microbial community composition and nitrifier populations, with higher loads promoting distinct microbial communities and increased ammonia and nitrite levels.
