Just purchased! Nice interface. I have been using Aquarimate and its been great for logging water test results and allowing each tank its own profile (to record livestock, expenses, notes). Especially useful is their statistics feature with allows you to enter the parameters you wish to track and it instantly develops a timeline graph for you
The downside of it though is that it was reef centric designed. No really dosing involved. Would love to be able to input dosing, continue tests, and then graph them to see the relation.
So basically if you could incorporate some of their features into your own you will have made a perfect product....would be extremely useful.
