I have been running this device for almost 8 months now to monitor and control my alkalinity for about 7 months now. I run a calcium reactor for 90 to 95pct of my system needs and the rest is managed by kalk dosed through aquawiz!
Aquawiz measures KH every hour and adjust the dosage of kalk based on the demand of the system. So the KH of my system remains steady through out the day. Also there is a maximum limit of the solution per day you can set so that it doesn't accidentally overdose.
This is how it works. The dosing pumps built into it pulls in water from the aquarium and then measures PH. It measure the pH of the tank sample after aeration and the standard seawater stored in the devise after aeration every time it takes a reading. The built in processor then calculates the KH based on the PH difference. The measurement is done every hour but you can adjust it to less number of tests based on your requirements. The current KH reading can be seen on the screen on the device. The device also sends data to the Aquawiz server and you can view all of the data on their website.
Finally the device monitors the health of the PH probe. It will display the health on the screen and also on the website.
Besides not needing reagents, these are the additional benefits
1. Calibration process is very simple. There‘s no need for pH calibration or dosing calibration. You only need to test the aquarium’s KH once a month and enter the data into the website. Since no reagents are needed, you also don‘t have to deal with replacing bottles or containers.
2. The error margin is less than 0.03, outperforming most brands.
3. With the built-in dosing system, since it tests every hour, the KH can be corrected to the target value every hour, resulting in minimal KH fluctuation.
This is a test I conducted on a bucket of water. Accuracy was within .03dkh!
The brand has been on the market for four years, with sales in China surpassing all other brands. This year, Fauna Marine has become the exclusive distributor for Europe.
The principle of this machine is different from traditional methods. The margin of error is controllable. If the water in the reservoir has only a small difference from the machine’s target value, even after a month without calibration, the error will only be within 0.2 dKH. It won‘t result in a significant error due to uncalibrated pH.
**Factors that affect the stability of reference seawater**Stability in reference seawater quality is crucial for accurate KH measurements. The KH value and salinity of reference seawater should ideally be close to the target KH value and salinity. It is recommended to use aquarium seawater that has reached the target KH value, natural seawater, or seawater aerated with a protein skimmer as reference seawater. Note that the KH value of some aquarium seawater may not be stable during static conditions, rapidly decreasing and causing inaccurate KH measurements.
**Contamination of reference seawater:**During measurements, since the same pH probe is shared in the left test tube, a small amount of reference seawater may mix with the aquarium seawater, causing the KH value of the reference seawater to gradually approach that of the aquarium seawater. If the long-term difference between the KH values of the reference seawater and the tank aquarium seawater exceeds 1.0 dKH, it is recommended to replace the reference seawater and calibrate the KH. Alternatively, choose to
calibrate every one week until the KH of reference seawater approaches that of the tank seawater. If the long-term difference is less than 0.4 dKH, calibration can be extended to about once a month. In general, the drift of KH measurement due to contamination is about ~0.002 / (timesX∆KH). ∆KH = (Reference KH - average Tank KH). If ∆KH = 1.0 dKH, and measured 100 times (~4 days, 1 time per hour), there will be 0.2 dKH drift. If ∆KH = 0.1 dKH, and measured 1000 times (~41 days), there will be 0.2 dKH drift.
Calibrating once a month is very simple for me. I just manually measure the KH of the aquarium and enter it on this page. No other calibration steps are needed, which I find very convenient.
