Stability
Stable parameters are usually safer than chasing a perfect number. Read pH, GH, KH, nitrates, CO2 and stability before choosing species or correcting water.

Cloudy aquarium water: likely causes and useful actions
Cloudy water does not always have the same cause. Timing, color, tank age and water tests help choose a measured action.
In this guide
Understand water
Guide to cloudy aquarium water: young tank, bacteria, substrate, filtration, suspended algae and maintenance.
Aquarium algae
Identify algae, understand their causes and correct the tank balance without making the problem worse. Choose plants by height, light, substrate, growth speed and water parameters.
Routine
Small regular actions are safer than sudden large corrections. Always relate the observation to the age of the tank, water tests and recent changes.
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. Read pH, GH, KH, nitrates, CO2 and stability before choosing species or correcting water.
Context
Always relate the observation to the age of the tank, water tests and recent changes. Identify algae, understand their causes and correct the tank balance without making the problem worse.
Choice
Open the detailed profiles before buying or treating anything. A good choice is also knowing when the aquarium is not suitable.
