**FISH ENCYCLOPEDIA**
Hundreds of species of marine fish and invertebrates, with their names in Turkish and English. Each species includes minimum aquarium size, temperament, reef compatibility, feeding habits, group needs, and origin. Most importantly, there are warnings to keep in mind for each species, so you can see how a creature will behave when it grows up before buying it. You can also list suitable species by entering your aquarium size and preferences.

**AQUARIUM CALCULATOR**
Enter the measurements, and it will calculate the rest: net water volume, required salt amount, live rock, sand, total circulation, circulation pump, heater power, skimmer capacity, and lighting. It also takes sump volume into account. Supports metric and imperial units.

**PARAMETER MONITORING**
Record temperature, salinity, pH, KH, calcium, magnesium, nitrate, and phosphate values. Color-coded status indicator based on reference ranges, daily and weekly percentage change, trend graph, and historical data table. You can log in with your Google account and back up your data to the cloud, accessing it from different devices.
