What does the standard EXIT result cover?
The standard three-day course is 20 drops per 100 L on day one and 10 per 100 L on days two and three. Extensions are not chosen by this tool.
Worked examples
These illustrations use 100 L of measured water, without a decor deduction. Choose the matching stage or formulation above for your own water volume. They do not select a treatment or establish livestock suitability.
3-Day Course
| Stage | Amount or action for 100 L |
|---|---|
| Day 1 | 20 drops (or 1 mL) |
| Day 2 | 10 drops (or 0.5 mL) |
| Day 3 | 10 drops (or 0.5 mL) |
Drops are rounded under this product’s measurement policy; mL uses the unrounded source amount. Choose one measuring method—do not add both. A drop size from another bottle is not interchangeable.
Example only. Your calculation above uses your own inputs. Small amounts and powder fractions still need equipment that can measure them reliably.
Before you measure
Inspect the full leaflet for filtration and water-change instructions. EXIT can stain silicone and discolour water. A visible improvement does not by itself select a new course.
Product-specific checks from the calculation record
- EXIT may discolour water and stain silicone. Extensions are not selected automatically.
Should I change temperature or extend treatment automatically?
The calculator changes neither. Check the diagnosis and manufacturer instructions rather than applying a universal heat or repeat-dose rule.
