"WE CYCLED OVER 40 DISPLAY AQUARIUMS IN OUR SHOWROOM WITH COLONY AND NOW SWEAR BY IT." - Matt Fry, Director Charterhouse Aquatics, London. ATM UK demonstrates the cycling power of ATM Colony Professional Grade Nitrifying Bacteria.
This tank was set up with no live rock, no pre-seeded media, or any other items that could contribute to the establishing of the nitrogen cycle. This is how it is done on the TV show, for any that still have questions on this.
This video shows a time interval that begins on March 14th and ends on March 19th.
NOTE: The nitrate readings in the video are indicative to the color of the test kit.
