Aquarium Ammonia Calculator

I created this aquarium Ammonia calculator to help with figuring out how much Ammonia to add during a fishless cycle.

  1. When using the calculator, remember to select the units you are using for your tank volume – Gallons or Litres.
  2. Enter the Ammonia concentration , it is usually printed on the bottle somewhere.
  3. Enter the current PPM of Ammonia in your tank and your desired PPM of Ammonia to dose up to.
  4. The output is is mililitres (ml) and drops. Drops are useful if you have a smaller tank or need to add small quantities.
