CHEZURAquarium decisions A filter can capture cells or fragments, but it cannot by itself correct the light, nutrient and maintenance conditions that sustain growth.
Green water is suspended and circulates; filaments and surface films grow attached and reach the filter only after removal.
Capturing detritus can help indirectly by exporting material from the system.
Adjust photoperiod gradually, avoid excess food, clean glass and prune affected growth. Keep the routine predictable.
Do not change light, fertiliser, media and water all at once; record one intervention and assess it.
| Situation | What to do | Why |
|---|---|---|
| Green water | Review light and nutrients | Standard media may not retain it |
| Filaments | Remove and correct conditions | They remain attached |
| Visible detritus | Improve capture and export | Lower available load |
After review light and nutrients, measure or observe Green water again with the same method. Record Stable control matters more than sterility. as well; if neither changes as expected, revisit the diagnosis before adding another intervention.
