I don't really need it.plecoguy said:see if you cant find the product called "Bio-Spira" my work just started selling it, i work at a private fish shop, and aparently its the only product with an instant cycle. we had some lady test it for us and she put the bio-spira in a brand new tank with a good amount of fish and she had one small ammonia spike, but nothing bad enough to really do anything...
