From the developer:
With our software it is possible for you to gather all data, which comes up when keeping and breeding fish, plants and invertebrae. With our software, you always have an eye on what is going on in your tanks, what trends in the waterquality come up or even why sudden breeding successes occurred. Do you remember, when you last changed water in one of your tanks? Or when the lights from your tank have to be changed to prevent algae-growth?
