CHEZURAquarium decisions Solids restrict sponge pores until airlift circulation falls. Cleaning restores passage without sterilising the habitat.
Compress and release until coarse waste falls and water passes. Avoid soap and hot water.
With two units, alternate service dates.
Inspect diaphragm, tube, check valve and diffuser before blaming foam.
Confirm flow and valve orientation after assembly.
| Situation | What to do | Why |
|---|---|---|
| Foam collapsing | Overlap replacement | Keeps mature surface |
| Few bubbles | Check air circuit first | Cause may not be clogging |
| Two sponges | Alternate cleaning | Retains capacity |
After overlap replacement, measure or observe Foam collapsing again with the same method. Record Low bubbles may be an air fault. as well; if neither changes as expected, revisit the diagnosis before adding another intervention.
