A handy tool to keep track of all of the vital information related to your aquarium together with an in-depth library of species to ensure you never get caught short for an impulse buy. Main features - • An encyclopaedia of over 800 species of marine fish, invertebrates and coral • Testing journal to keep track of over 30 of the most vital parameters • Trends to plot graphs and visualise how stable each parameter is over time • Inhabitants diary to keep track of your latest additions including information such as how long you've had it, was it feeding in store beforehand, where was it purchased from and much more. • Dosing log top keep track of any chemical additions to your tanks to help keep up to date on doses and keep stability where it should be • Reminders with device notifications so you never miss an important event • Water change journal to keep a detailed log such as when, how much, salinity etc. of your water changes performed • Maintenance log to remind you of your last maintenance actions completed per tank • Compatibility of species - A simple, brief run down of what species are typically safe, tolerant or not safe to be housed with others • A simple set of useful calculators such as alkalinity conversions, Celsius to Fahrenheit or gallons to litres and more. Keeping track of our aquariums can ultimately be one of the most important parts to the 'reef keeping' hobby. Maintaining husbandry tasks, testing, stability, water changes, inhabitant stats etc. are all vital to keeping successful aquariums. Pocket Marine was designed to make inputting, storing and keeping all information with you at ease. Often, any issues that we have with our aquariums can be linked to actions that were performed a short time beforehand. For this reason, a log of changes made, actions performed or additions can be vital when trying to decipher a problem that may be in play. Pen and paper has always been a great way to keep this information at hand but, Pocket Marine offers a place to store this somewhere that, this day and age, is with us at all times. Not just for tracking events. Pocket Marine is a great way to help you log your inhabitants into specific tanks, record your latest water change for your mixed reef tank or simply log your latest maintenance action performed on the fish only office tank. Recording your information couldnt be easier and keeping it on your mobile device saves on that frantic search incase of needing the information at a later date. Help with that last second impulse buy at the store. With an in depth library of over 800 species of fish, invertebrates and coral and being added to daily, you will always have the information on hand that you need to make that informed decision on a purchase. We hope you enjoy using the app and that we can help with your success in the hobby and welcome any feature requests you may have. Happy Reefing!
