Understand water
pH, GH, KH, nitrates, CO2 and tank stability. Stable parameters are usually safer than chasing a perfect number. Always relate the observation to the age of the tank, water tests and recent changes.
Aquarium keeping guide
Starting an aquarium without skipping steps
A successful aquarium rarely starts with a shopping list. It starts with coherent volume, understood water, adapted plants and a population chosen after the tank has matured.
In this guide
Plan before acting
Use this guide to compare the real needs of a first aquarium before changing the aquarium.
Aquarium substrate
Sand, gravel, nutrient or technical substrate according to the project. Small regular actions are safer than sudden large corrections. A good choice is also knowing when the aquarium is not suitable.
Fish
Compare size, volume, temperature, pH and behavior. Check the minimum volume, water and behavior before choosing. Open the detailed profiles before buying or treating anything.
Observe and compare
Look at volume, water, behavior and warning signs together instead of deciding from one detail.
Stability
Stable parameters are usually safer than chasing a perfect number. pH, GH, KH, nitrates, CO2 and tank stability.
Routine
Small regular actions are safer than sudden large corrections. Sand, gravel, nutrient or technical substrate according to the project.
Choice
Open the detailed profiles before buying or treating anything. Compare size, volume, temperature, pH and behavior.
Avoid common mistakes
Most failures come from rushing, mixing incompatible needs or correcting everything at once.
Needs
Check the minimum volume, water and behavior before choosing. Compare size, volume, temperature, pH and behavior.
Limits
A good choice is also knowing when the aquarium is not suitable. pH, GH, KH, nitrates, CO2 and tank stability.
Aquarium algae
Identify algae, understand causes and act sustainably. Choose by height, light, substrate and parameters.
