LibreAquarium

SME LibreAquarium is an Aquarium management system with a Simulation Model Engine (SME) that makes a prediction of the possible measurement values for the different pollutants that affect to these aquatics systems (NO3,PO4, Fe). 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. SME LibreAquarium helps to daily maintenace of the aquarium with habitants control(fishes,plants, invertebrates), expenses, statistics, alarms, etc.
