One restricted ammonia thesis does not create a safe tank threshold
The evidence library is allowed to change in public. This page preserves the revised boundary, why it moved and which guides were affected.
What changed
The nitrogen gap now records an official 2007 thesis abstract that reports chronic total-ammonia growth and reproductive comparisons in Neocaridina denticulata.
Why it changed
The complete 79-page thesis is restricted. The public record does not expose the chronic duration, vessel replication, animal denominators, water pH and temperature, exposure verification, exact statistical tests or derivation of the abstract-labeled maximum acceptable concentration. The abstract therefore changes the discovery map but cannot validate a care target, intervention trigger or N. davidi threshold.
Sources reviewed for this change
Affected practical guides
A public change is not automatically a retraction. A source may be added, a scope narrowed, a gap refined or an error corrected. The current guide and registry record own the current wording.
