After constantly forgetting to dose my planted aquarium with fertilizers i decided to find a way to automate this process. I built an arduino auto doser to keep my little eco system thriving. This system dosing a specified amount of fertilizers via 3 dosing pumps at a set time each morning. I have the schematics and the arduino sketch posted at http://fishtankprojects.com/diy-aquarium-projects/arduino-controlled-dosing-pumps.html
