Anyone sitting on the fence over buying an aquarium controller has one more selling point to give their spouse. The 40% off sale brings the GHL Profilux kit price down to a manageable $898, well under $1,000. You can enjoy the savings or go wild and buy the new touch screen control ($350) and do some customizing with the $600 difference. The package comes with PH, conductivity and temperature sensors, along with the standard built-ins like illumination and process timers. The GHL optical ATO sensors are a no brainer option, as well as an ORP sensor. Anyone using the balling method will love the Profilux dosing pump system. GHL remains the most aggressive in new product releases in the aquarium controller market. The hits keep coming and the rare sale really makes it hard to say no. The sale is only on until July 10th, so as they say on TV, “act now while supplies last”.
