I can not keep silent any more.
I would not consider anything said in this thread by kissfn to have any scientific validity at all. There are many other totally false and undocumented statements being made by a number of other posters as well.
ianho- can you please provide evidence that Sea Life Aquariums own any part of Dr. Hovanec's businesses or processes as you have stated in this thread.

The nitrifying bacteria in "Turbo Start" are not the same as "Biospira" (Nitrospira), but instead a different type that does the same thing (converts nitrite to nitrate) called nitrobacter.
The reasearch by Dr. Hovanec in 1998 would seem to have proven this is incorrect in reference to aquariums.
Hovanec, T. A., L. T. Taylor, A. Blakis and E. F. DeLong. 1998.
Nitrospira- Like Bacteria Associated with Nitrite Oxidation in Freshwater Aquaria. Applied and Environmental Microbiology Vol. 64, No. 1: 258-264.
Abstract: Oxidation of nitrite to nitrate in aquaria is typically attributed to bacteria belonging to the genus
Nitrobacter which are members of the alpha subdivision of the
Proteobacteria. In order to identify bacteria responsible for nitrite-oxidation in aquaria, clone libraries of rRNA genes were developed from biofilms of several freshwater aquaria. Analysis of the rDNA libraries, along with results from denaturing gradient gel electrophoresis (DGGE) on frequently sampled biofilms, indicated the presence of a putative nitrite-oxidizing bacteria closely related to the genus
Nitrospira. Nucleic acid hybridization experiments with rRNA from biofilms of freshwater aquaria demonstrated that
Nitrospira-like rRNA comprised nearly 5% of the rRNA extracted from the biofilms during the establishment of nitrification. Nitrite-oxidizing bacteria belonging to the alpha Proteobacteria subdivision (e. g.,
Nitrobacter spp.) were not detected in same samples. Aquaria which received a commercial preparation containing
Nitrobacter species did not show evidence of
Nitrobacter growth and development but did develop substantial populations of
Nitrospira-like species. Time series analysis of rDNA phylotypes on aquaria biofilms by DGGE, combined with nitrite and nitrate analysis, showed a correspondence between the appearance of
Nitrospira-like bacterial ribosomal DNA, and the initiation of nitrite oxidation.
In total, the data suggest that Nitrobacter winogradskyi and close relatives were not the dominant nitrite-oxidizing bacteria in freshwater aquaria. Instead, nitrite oxidation in freshwater aquaria appeared to be mediated by bacteria closely related to Nitrospira moscoviensis and Nitrospira marina.

If anybody wants to do anything close to a scientific study of this subject you will need to keep a journal which provides daily readings of:
1. Water temperature.
2. pH level.
3. Ammonia level.
4. Nitrite level.
5. Nitrate level.
There should be no live plants nor any cycled material in the tank(s) as these will both interfere with results and thus invalidate them. A base level readings for the tank should be taken when it is set up.
In addition, information on the brand and quantity of any dechlor added should be recorded with dosing details included..
The type and manufacturer of all test kits or digital meters used should be recorded.
The type and dosing for any ammonia added or the presence or addition of fish should also be recorded with details.
The amount of any water changes done and if done, the new water going in should have its parameters recorded before it is added.
The specific bacterial addivte should be named. Under what conditions it was in when purchased ( ie refrigerated, in a temperature controlled environment etc etc.) The packaging date and lot number and expiration date should also be recorded. The dates/times for everything done should also be recorded.
In the end the true determinant of the validity of any piece of experimental research is that it provides sufficient details so that any other "researcher" can replicate the experiment using the same methods and get the same results.
In a nutshell, to all those folks who have said this, that or the other product worked or did not work, I say to you:
Prove It!
