Enter to Win an All-new GHL Doser 2!

ghl-doser_1While in Denver at MACNA 2014, we had the chance to meet Michael Hall of GHL Advanced Technology. He gave us the complete rundown on their all-new GHL Doser 2. Pre-orders for these new units began during MACNA and they will begin shipping during the later part of this month. However one lucky aquarist will win one of these new dosing pumps in GHL’s latest sweepstakes (details below).

This new dosing pump is reliably built with the high quality, long-life materials hobbyists are already accustomed to from GHL. Adding this reliability to the expansion and connectivity options and users will have a very capable product at their disposal. Here are some of the key features you can expect:

  • Connectivity via wifi or USB (using the free mobile app or software)
  • Fully customizable dosing schedules
  • LED status display with manual control on the unit
  • Integrated auto top-off (with auto water change capability)
  • Liquid level display and alarm for refill malfunction
