Who or what is Aquarium Maintenance Service? It was founded in 1966 and is one of the oldest aquarium cleaning companies in the country let alone the Sacramento Valley. We service commercial and residential properties ranging from 10 gallon aquariums to over 1000 gallons. No job is to big or to small that we haven’t been able to handle. We are friendly, knowledgeable, service oriented, and most importantly we love aquariums of all shapes, and sizes.
