The ProHobby™ Knowledge Library

The ProHobby™ Blog is a science-first reference library on aquariums and aquatic ecosystems.
Here you’ll find in-depth articles exploring system stability, ecology, water chemistry, biotopes, fish health, and long-term success across freshwater, marine, brackish, and hybrid environments. This is not a collection of quick fixes — it is a body of knowledge built around understanding why aquatic systems behave the way they do.
