We used the small sicce Syncra Nano for several months with different setups. First, we used it with our fluidized bed Ultra Reef ul-100e, then we used it as our osmolator pump along with the Hydor smart level control. It was very reliable, silent, and perfectly suited for the tasks.
The max height of the Sicce Syncra Nano
The first test we did was to measure the max height. The test was simple. We dropped the pump into a small aquarium with 14 cm of water inside, connected the pump to a plastic garden hose held vertically, and measured the height reached by the water column from the ground. We then subtracted the height of water in the aquarium. The max height is the distance between the two levels of water.
We obtained a reading of 81.5 cm inside the hose.
This picture shows the height of water inside the aquarium, it measured 14.2 cm.
So, for the sicce Syncra Nano we concluded that 81,5 cm – 14,2 cm = measured maximum height 67,3 cm (70 cm declared)
Output test of the Sicce Syncra Nano
Measuring the pump output is easy thanks to the new DigiSavant DIGIFLOW 6710M. We directed the flow from the pump towards the flow meter and read the result expressed in liters per minute.
We read, as you can see, 6.8 l/m, or 408 l/h, a value very close to 400 l/h declared by sicce.
Test of power consumption of the Sicce Syncra Nano
During the output test we also measured the power consumption with current clamp, but were unable to measure the power factor (more information here).
The power consumption was 0.014 amps or 3.08 watts (0,014 A x 220 V = 3,08 watt) higher than the 2.8 watts advertised.
Here in Italy, the price per kilowatt is 0.27 euro, so if we use this pump for one year, we will have to pay approximately (3.08watt*24*365/1000*0.27)=7.3 euro per year. Very inexpensive!
The noise test of the Sicce Syncra Nano
We measured the sound pressure at 1 meter away from the pump after it was placed inside the small aquarium we used for our test, and had no other equipment inside the tank.
First, we measured the ambient noise, it was 29.8 dB, very quiet.
Then we turned on our sound meter, which recorded a sound pressure of 30.3 dB, a value too low to be heard.
For this test, we used the VOLTCRAFT 320, a IEC 651 Type II digital sound level meter. Given the nature of the noise to be measured all measurements were performed with the attenuation curve dBA.
