## Reef Buddy Reviews in United States

### ***** "Review"
This is a great app!  Looking for parameters for multiple aquariums this works. Would like a general section for notes per aquarium.

### **--- "Used to not require an account"
Was great but now requires an account to use. This is not an app that needs any of my information in order for me to  track my parameters.
