I am setting up a new planted tank (my first one). I downloaded 6 apps, immediately rejected 2, didn't want to create an account to use a 3rd, and tried out the other 3 (incl this one). This one is the most complete for dealing with water parameters (completely customizable), maintenance tasks, and fertilizing my plants. There are some features that apparently aren't implemented yet (incl ads), but I went ahead and paid for the ad-free upgrade because I wanted to support this developer. 5 stars!

There is a learning curve, but the tool is powerful enough to make the effort worthwhile. Changing my review to 4.8 stars. Click the little arrow by your fish or plants to copy or move them. Developer is responsive. I wish more developers would wait to put in ads until the app was on the second version. I already paid to never see them. It would be awesome to be able to turn off or pause tasks. Perhaps tanks marked "not in use" would have their tasks paused and not show on the dashboard?

NEW EDIT: *Please add backup & sync! New phone and trying to put in a years worth of 9 tanks is impossible! I have an account, what's the point if we cant use it?!?* I've had this app for a long time and I love it. Add in everything you do, you'll find it really handy down the road when looking for patterns and the like. This is also the best app for having multiple tanks. I am able to go back and see what medications or additives worked, devices, didn't work, affected the pH, etc. etc. 5⭐

This feature will not be implemented in this version (something like that is planned for version 2). You can transfer data to new phone using local backup and then restore it on you new device. IF you need help/assistance please contect me via email:
