The reference  tool
for enthusiastic reefers.

- Record your tanks water parameters (chart or table view)
- Use a calendar with reminder functionality
- Calculate the amount of salt you need for your next water change
  or to adapt your tanks salinity
  (realistic data of nearly all available synthetic salt mixes included)
- Evaluate exact dosage of salts and liquid solutions
  for adaptation of Calcium, Alkalinity and Magnesium
  according H.W. Balling’s method.

- Convert units of all measured quantities of saltwater tanks
  (eg Salinity ↔ Density ↔ Conductivity)
