Feed & EC
EC readings do not match
First compare the test methods, then compare the numbers. A supplier’s extraction result and drainage from a fertigated crop describe different samples.

Are tank volume markings accurate enough for fertigation?
Verify the working volume before treating a tank line as a precise measurement.

Why the root zone matters
A stock made to the wrong volume changes nutrient delivery to all coir bags using it.
01 / OBSERVE
Three checks before you change anything
- Compare usable markings with an independent volume measurement appropriate to the tank.
- Read levels on a level base and account for internal fittings or unusable bottom volume.
- Record whether the recipe specifies water added or final solution volume.
02 / NARROW IT DOWN
What do you find?
Choose the closest observation for a suggested next check.
Markings differ from measured volume
Create verified working marks and update the preparation procedure.
Tank stands unevenly
Correct the support and recheck the marks before mixing.
Preparation basis is unclear
Confirm final-volume instructions with the recipe supplier.
03 / TAKE THE NEXT STEP
Leave with something useful
Document the calibration method and keep a repeatable filling reference.
Keep in mind
Do not assume a container’s nominal capacity equals the volume at every printed graduation.
