Aquarium Plant Fertilizer

Aquarium fertilizer calculator for planted tanks. Plan planted tank dosing with EI dosing or PPS-Pro. Calculate aquatic plant fertilizer amounts for dry salts, stock solutions and supported bottled fertilizers.

Spend less time working through fertilizer math. Enter your tank volume in liters or US gallons, choose your inputs, and see what each dose adds.

FOUR WAYS TO CALCULATE - Dry powder: calculate nutrient ppm from the amount you add. - Mixed bottle: enter your stock-solution recipe and dose volume. - Hit a target: work back from a nutrient ppm target to grams of dry fertilizer. - Bottled fert: scale supported manufacturers' label directions to your tank.

NUMBERS YOU CAN CHECK View the sources behind reference values and dosing methods. See nutrient contributions for dry salts and mixed solutions. Teaspoon amounts are approximate; calibrate them with your own scale. Bottled-fertilizer results show label doses rather than estimated ppm.

A ROUTINE FOR YOUR TANK Explore EI and PPS-Pro dosing methods. Pro adds unlimited saved tanks, dosing schedules, a Today view, dose history and optional local reminders.

The core calculator is free. Unlock Pro with one purchase, with no subscription. No ads or account required. Calculations work offline, and your aquarium records stay on your device.
