LibreAquarium
An aquarium management software with a Simulation Model System
...The simulator consults the recorded analysis to calculate a prediction of the NO3, PO4, Fe, that the these aquatic system produce.
It also uses a central (fish, plant and invertebrates) database to check if the actual parameters are Ok, depending on the species that live in the Aquarium.
With all the records, the Simulation Model predicts the algae risk too (low,medium,high) and the algae type(green,cyanotic.) using the Redfield coefficient.
Appart from that, the program tries to bring another modest contribution to Open Source Software and the World of Aquariums. ...
