eSHa EXIT for guppies: volume, records and treatment limits
By Richard James · Manufacturer sources reviewed 28 October 2026
This guide helps you prepare a calculation for a tank with adults and fry. It does not prescribe a medicine for guppies or create a special species dose. A spot-like mark or rubbing is an observation to record, not a confirmed diagnosis from this website.

Start with the aquarium you will actually treat
List adults, fry and any other residents before choosing a treatment setup. A guide about guppies does not establish compatibility for every animal sharing the water.
Write down the exact bottle, all products already added, the water-test results and the reason treatment is being considered. If the cause is uncertain or the fish is deteriorating, seek appropriate fish-health advice.
A water-volume example
A keeper records 36 L of actual water in a tank sold as 45 L. Enter 36 L as measured water. Do not deduct the decor again.
This is a worked input example, not a clinical case or evidence of treatment success. Check litres versus US or UK gallons before using the result.
Use the product instructions alongside the result
Read the EXIT course guide for preparation, compatibility and course limits. Open the eSHa EXIT calculator only after checking the exact bottle and application.
- Keep each displayed day or application separate.
- Measure the quantity with suitable equipment; do not guess an unmeasurably small fraction.
- Record what was actually added and when.
- Check the manufacturer instructions before changing water, combining products or repeating a course.
What this guide does not decide
There is no automatic half-dose, double-dose, heat treatment, salt addition or recovery deadline based on the species name. The linked manufacturer instructions take priority over a general species shortcut. If your bottle differs from the calculator, resolve that difference before dosing.
