MACI Books | Living Aquariums and Clear Criteria

The MACI collection

The website gives direction. The books develop the criteria, nuance, and full reading of the system.

You do not need to read everything at once. Choose the entry that matches your situation and let the collection unfold step by step.

The practical entry · Start here to build or turn around

MACI — The Easy-to-Run Manual

Organises the setup or recovery of a living aquarium without turning it into a chain of corrections.

Start with this if: You are setting up, turning around, or want a practical entry before getting lost in detail.
It is not for: Someone looking for a rigid weekly checklist without observing the aquarium.

Read before acting · For an active problem

Helps you read symptoms before acting and separate real emergencies from rushed interventions.

Start with this if: You already have gasping fish, cloudy water, algae, melting plants, or values that are difficult to interpret.
It is not for: Someone who does not have an aquarium yet and only needs an initial route.

Conceptual entry · Understand the framework

Explains how to observe the aquarium as a living system, not as a collection of products or automatic tasks.

Start with this if: You want to understand the conceptual foundation of MACI and stop maintaining by reflex.
It is not for: Someone who needs an urgent answer for an active problem.

Design and internal capacity · Go deeper

Develops living structure, margin, plants, colonised surfaces, circulation, gradual bioload, and continuity.

Start with this if: You understand the foundation of MACI I and want to go deeper into designing aquariums with greater internal capacity.
It is not for: Someone who still needs a practical starting guide or an urgent answer.

Cases over real time · See the evidence

Brings together cases, continuity, and observations from real aquariums as documentary development of the framework.

Start with this if: You want to follow real cases and consequences over time behind MACI.
It is not for: Someone who wants to start from zero with an immediate practical guide.
