LibreAquarium
An aquarium management software with a Simulation Model System
...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. SME LibreAquarium helps to daily maintenace of the aquarium with habitants control(fishes,plants, invertebrates), expenses, statistics, alarms, etc.
