Ich-X for guppies: volume, records and treatment limits

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 Ich-X handling guide for preparation, compatibility and course limits. Open the Ich-X 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.
