There is an app for the iPhone (possibly android too) called AquaPlanner. I love it you can all kinds of details about your tanks(fresh, marine, or reef). There are features that let you log your water tests, equipment, and inhabitants. It is a must have, y'all will like it. Let me know if y'all do get and tell me how it works for you!
