We were alerted to a new app in the Apple App Store named Reefdoser Pro.  This is available for the Apple iPad and features an incredible amount of logging and statistical analysis tools for the advanced aquarists.  Despite the huge number of possible inputs, you can use this app to identify common causes of pH issues, Alk/Ca balance issues, balling light, as well as long term trending for Phosphates and Nitrates.  Basically the app depends on you putting in your test results, but it gives you a very nice interface and explanation of what your current chemistry is and how to dose to get to the ideal levels.  If you’re like us, you keep some sort of computer or iPad near your tank to record this information and Reefdoser Pro seems like a great fit if you are struggling to understand what is going on with your water chemistry.  Check it out now on Pixelwand’s website.
