Dose is a new, free iPhone app from Seachem which allows the user to easily regulate their aquarium’s chemistry. I think it is safe to say that most power aquarium dosers often guesstimate how much product to add and determine the affect by testing the outcome later, I know we do. Dose takes the guesswork out of how much seachem product is required to change certain chemical concentrations, not the least of which is Calcium and Alkalinity. The planted tank enthusiasts can also benefit from the gravel and freshwater dosing calculations performed by the iApp. The program is designed for use with Seachem products but the output will likely still be accurate when used with similar calcium chloride or Carbonate/Bicarbonate based additives. Either way we’ll be reaching for the Seachem much more often with Dose on our phone. We’ve only had Dose loaded for a few days but we’ll be sure to let you know how well the program works in the real aquarium world. The app is available now at no charge in the iTunes App Store.
