Seeding a Tank/Filter
by Dr. Adrian LawlerExtracted from the staff Operational Handbook which Dr. Lawler wrote as Aquarium Supervisor for the J.L. Scott Marine Education Center and Aquarium, of Biloxi, MSAquarticles

A tank should be "seeded" (inoculated with waste-oxidizing bacteria) when: l. A remodeled tank is stocked-out. 2. An ammonia build-up occurs when: - A tank is over-fed, or animals throw up their food. - Air is left off a tank for too long a time and the biological filter bacteria die off. - A tank's filter is cleaned too well, discarding too many bacteria. - An organism gets killed or dies (does not survive shedding, injury, or other causes of death) in a tank. - Too much city water (high in chlorine and ammonia) is added to a tank killing biological filter. - A treatment used in tank kills off biological filter.
Excess ammonia should be decreased by water change or addition of AmQuel prior to re- seeding a tank.
Bacteria for seeding a tank can be obtained by: - Getting a commercial product (Fritz-zyme, other commercial products). - Backflushing a sand filter. - Squeezing out sponge filters. - Siphoning from an undergravel filter. - Adding coral or gravel from an established filter. - Adding filter floss from an established filter.
Bacteria should be obtained from a tank with a similar salinity to the tank being seeded. Seed should not be gotten from a tank having recent problems with ammonia, algae, or disease.
If sufficient bacteria are added, a new tank (or re-seeded tank) can be set-up without a three to four week "cycling" process.
Experience plays a great part in ascertaining the amount of debris, etc. needed to seed a tank - a 210 gallon tank needs two to three one-gallon scoops of coral (gravel) from an operating tank in order to properly inoculate it. Spread coral (gravel) evenly over tank bottom.
As the bacteria for a biological filter need food (= waste products) in order to survive and grow do not inoculate a tank and wait one or more days prior to adding organisms.
