Calculation details
Formula and methodology
See the exact math used to produce the result.
Medication amount = actual treatment gallons divided by 10, multiplied by the label dose per 10 gallons.
Before acting
Assumptions to check
Review the real-world details that can change the estimate.
This calculator only scales the product label amount. Confirm actual water volume, the product and condition being treated, repeat-dose timing, water changes, filtration instructions, and species or invertebrate sensitivity.

What to verify before acting
Use the arithmetic only when it matches the medication label and treatment plan. Do not use the result to diagnose disease or override label restrictions.
When to use this calculator
- Scaling a verified label dose to actual water volume
- Checking milliliter arithmetic before treatment
- Recalculating a label amount for a quarantine tank
Tips for better estimates
- Verify the medication name, concentration, and label basis before entering a dose.
- Use actual treatment volume when it is known.
- Observe livestock and follow label instructions for filtration and repeat dosing.
How this calculator is reviewed
This page is checked for inputs, formulas, examples, assumptions, topic fit, and related links. For this calculator, the review also covers tank volume, stocking level, filtration, water changes, heater sizing, substrate depth, product labels, and species needs.

Worked example
Example inputs: Water volume: 29 gallons; Dose per 10 gallons: 5 ml. With those values, the calculator returns 14.5 ml. Use about 14.5 ml based on the label dose.
Example scenarios
- Use actual water volume after displacement rather than the display-tank size.
- Enter the dose exactly as written per 10 gallons on the product label.
- Recalculate after a water change only when the treatment instructions call for it.

FAQs
Aquarium Medication Dosage Calculator questions
Should I round the medication dose up?
Do not blindly round up. Follow the product's measuring precision and label directions, especially for sensitive fish, plants, or invertebrates.
Should I use the tank's advertised gallons?
Actual treatment volume is better because substrate, rock, equipment, and empty headspace reduce the water present.
Can this calculator identify the right medication?
No. It only scales an entered label dose. Confirm diagnosis, product suitability, contraindications, and treatment instructions separately.
