Doesn't do a thing!,
This review is from: API Quick Start 118ml (Misc.)
I bought a bottle of this from my local fish shop and having fully tested it (used nearly a whole 237 ml bottle before giving up) I can thoroughly say it either does nothing whatsoever on jump starting the nitrogen cycle or does little enough to be unnoticeable.
I have since bought a new product called Tetra Safe Start which has been very successful for me (0 ppm Ammonia and Nitrite after just 24 hours in my case).
I recommend either saving yourself the money from this product and spending it on Tetra Safe Start or use a search engine to search for information on a 'fishless nitrogen cycle' and follow the steps to complete it naturally.
