Choose by your situation, not by the whole collection
You do not need to buy every book to begin. If your aquarium already has problems, start with the Aquarium Diagnostic Manual. If you are setting up or redesigning the system, start with Easy-to-Run.
I have a problem: see DiagnosisI want to start well: see Easy-to-Run
MACI I, MACI II, and Evidence are the natural continuation for readers who want to go deeper into the full framework.
MACI Books
MACI books develop the framework in depth. The website orients; the books explain the criteria, nuance, and full reading of the system. If you do not know where to begin, this page orders the route.
Which Book Should You Read First?
If you are setting up or redirecting an aquarium
MACI — The Easy-to-Run Manual
The practical door. Start here if you want to set up or correct a living aquarium without depending on constant rescues, fear-based products, or copied routines.
If you already have problems and do not know what to touch
MACI — Aquarium Diagnostic Manual
For learning to read symptoms before acting: cloudy water, algae, gasping fish, melting plants, confusing values, and rushed decisions.
If you want to understand the framework
MACI I
A conceptual entry into the MACI framework: stop maintaining by reflex and learn to observe the aquarium as a living system.
If you want to design aquariums with less dependency
MACI II
Designing to disappear. The second volume of the MACI corpus develops how to build aquariums that do not depend on constant rescues, automatic routines, or fear-based corrections.
If you want to see the evidence
MACI — Evidence of the System
Cases, time, and observations from real aquariums. The documentary development of MACI evidence, complementary to the videos published on TikTok.
MACI Catalogue
MACI — The Easy-to-Run Manual
Start with this if… you are setting up, redirecting, or want a practical entry before getting lost in details.
What problem it solves: it orders the setup and recovery of a living aquarium without turning it into a chain of corrections.
Who it is not for: someone looking for a rigid weekly checklist without observing the aquarium.
MACI — Aquarium Diagnostic Manual
Start with this if… you already have gasping fish, cloudy water, algae, melting plants, or values you do not know how to interpret.
What problem it solves: it helps read symptoms before acting and separates real emergencies from rushed interventions.
Who it is not for: someone who does not have an aquarium yet and only needs to choose an initial setup route.
MACI I
Start with this if… you want to understand the conceptual base of the framework and stop maintaining by reflex.
What problem it solves: it explains how to look at the aquarium as a living system, not as a sum of products or automatic tasks.
Who it is not for: someone who needs an urgent answer for an active problem before reading the framework calmly.
MACI II
Start with this if… you already understand the foundation of MACI I and want to go deeper into designing aquariums with greater internal capacity.
What problem it solves: it explains how to think about the aquarium so it depends less on constant intervention and more on living structure, margin, plants, colonized surfaces, circulation, gradual bioload, and continuity.
Who it is not for: someone who still needs a practical starting guide or an urgent answer to an active problem.
MACI — Evidence of the System
Start with this if… you want to see cases, time, and observations from real aquariums behind the framework.
What problem it solves: it brings together documentary development, continuity, and visual evidence that complements published videos.
Who it is not for: someone who wants to start from zero with an immediate practical guide.
You Do Not Need to Read Everything at Once
If you are a beginner, start with the manual. If your aquarium already shows confusing signs, start with diagnostic. If you arrived from TikTok and want to understand what supports the framework, go to MACI I or Evidence of the System.
