CHEZURAquarium decisions The same volume can leave as one fast jet or many slower streams. Livestock and debris experience very different systems.
A small nozzle accelerates; a spray bar shares flow, though holes may not discharge evenly. Diameter, spacing and feed direction matter.
Lily pipes create broad patterns but biofilm changes their shape and needs cleaning.
Deflect for slow swimmers, angle upward for surface exchange, and avoid needless agitation in CO₂ injection without sacrificing oxygen.
Recheck after cleaning because outlet geometry is restored.
| Situation | What to do | Why |
|---|---|---|
| Jet stresses fish | Add spray bar or diffuser | Lowers local speed |
| Still surface | Angle upward | Transfers momentum |
| Long dead zones | Split returns | Extends coverage |
After add spray bar or diffuser, measure or observe Jet stresses fish again with the same method. Record Dirty holes change distribution. as well; if neither changes as expected, revisit the diagnosis before adding another intervention.
