Maintaining KH level (alkalinity) in a tank can be challenging. The conventional method of alkalinity measurement is to mix an acid such as HCL with a sample solution of tank water. And record the change of PH values before and after the mixing. The alkalinity of the water sample is then obtained as a function of PH value changed, and the amount of acid added. It’s a complex and time consuming process that you may have to perform over and over. Say good-bye to cans and bottles of test solutions and the tedious daily routine! This revolutionary invention, AquaWiz KH controller™, automatically measures and optionally maintains the KH level in your tank. No test solution needed. All you need to prepare is a “reference solution” that can best sustain life in your tank. It can be your existing tank of seawater with stable alkalinity. The reference solution is recycled and reused during the whole measurement process. No wastewater is dumped, and no acid solution is produced. It’s an environmentally friendly solution that can do both KH measurement and KH control. No test solution needed ! No pollutant produced ! No more test solution shortage. Coral consumes different amounts of KH per hour. It is necessary to measure KH every hour. Resumes automatically after power outage. New water level control for reference water reservoir. Controls KH through a built-in dosing pump to dosing KH solution. KH to PH converting BNC plug to enable reading and control KH by a PH controller. Specific PH electrode, no extra calibration step is needed. Detects the aging of the PH electrode, automatically reminds for replacement. No more worry when you are out of town ! Notify through email when out of specification. Check KH status remotely in a line chart through www.aquawiz.net. Measurement intervals can be set to 1~6 hours through the web interface. Enclosed motor and pump, and sleep timer setting. Open lid design for easy installation and maintenance. Before you use Aquawiz make sure there is no stray voltage in your system from other devices as this will affect the performance of the device.
