A number of products are on the market that help start the cycling process in a tank. Some contain a quantity of the nitrosoma and nitrobacter bacteria which will help cycle your tank faster (some as fast as 1 day) than normal. Others contain enzymes which help naturally occurring bacteria grow more rapidly. Some products are added only at set up, others need to be replenished periodically.
