The new Kamoer F4 PRO Wifi Doser Liquid Dosing Pump is the latest state of the art controllable dosing system from Kamoer. Each unit includes a Wifi connection which allows the doser to be controlled via iPhone or Android. Keep Your Parameters Stable Easily schedule a dosing regimen to keep water chemistry within ideal ranges. You can automate 2-part calcium and alkalinity, Kalkwasser, trace elements, live or prepared foods, and even fertilizers and liquid CO2 if you have a planted tank. Easy-to-Use Mobile App Download the free app for your iOS or Android device for easy wireless control. Software updates are a breeze and can be pushed to the F4 PRO via WiFi. The user-interface is friendly and intuitive to help you get up and running quickly. Robust Dosing Capabilities 3 operational modes—Auto, Manual, or Custom—make it easy to start dosing your tank, even if you've never used an automatic dosing pump before. You can set start and stop times, select how much to dose over a period of time, alternate days that you dose, and even delay channels to prevent chemical interference. Battery Backup Included After dialing in your programming to automatically dose you aquarium with precision, the last thing you'd want to do is to have to start over in the event of a power outage or if the unit is unplugged. That's why the brilliant minds at Kamoer equipped the F4 PRO with a battery backup. In the event of a power loss, all your settings will be saved!
