About Chezur

What Chezur is

Chezur is an independent publication about aquarium planning, filtration, water and responsible fish care. Its calculators, troubleshooting guides and documentary product profiles support decisions that can be checked against the real aquarium; they do not replace observation or professional advice.

Who publishes the site

Jaime Castillo is the owner and editorially responsible person behind Chezur. Naming the publisher makes responsibility for content, corrections and commercial decisions visible; it does not imply a qualification, professional role or product test unless a page states and demonstrates one.

How the project is funded

Chezur is funded by clearly identified Google AdSense advertising and, only where a link is labelled as affiliated, a possible commission. Payment does not increase the reader’s price and no advertiser, shop or platform may approve an editorial conclusion.

• Advertising is visually separate from editorial material.
• A compensated link is disclosed beside the relevant action.
• A document-based profile is never described as hands-on testing.

Scope and responsibility

The material is educational. Signs of disease, poisoning or suffering require a veterinarian experienced with aquatic animals. Fish, plants, invertebrates and aquarium water should never be released into the natural environment.
