About AquariumHQ
Structured, sourced intelligence on aquarium fish, invertebrates, plants, water chemistry, compatibility and problems — with the evidence and the uncertainty shown.
What this is
AquariumHQ organises aquarium knowledge into structured intelligence: organisms, plants, water chemistry, equipment concepts, problems and the relationships between them. The aim is that somebody can understand an aquarium as an interconnected biological and environmental system rather than by reading isolated care articles.
It is not a blog, a product-review site, a retailer or a directory. There are no affiliate links, no brand rankings and no user accounts.
Current state
The catalogue is deliberately partial and always will be — it grows weekly, and what is missing is documented on the coverage page rather than hidden.
