OK, lets say I would set up a new tank with a "sterile" substrate, heavily
planted, no media or sponges in the filter, no fish....just Co2, an
occasional "shot" of ammonia in the substrate and maybe some trace elements
when they become depleted for the first couple months.
In your opinion, would this procedure have any advantages over adding N and
P fertilizers to the substrate (as far as algae outbreaks are concerned)
when cycling a new tank?
Also, would any nitrite spikes be a major concern to the plants?
