The four photos on the top show a 30cm (12") cubic tank made of starfire glasses. Two ComboRay CR-30 units are mounted on top of this tank with the specific rotatable mounting stands. One can see that the tank is so bright under the two fixtures consuming only 24W. One of the units is composed of 3 x 7,000K CW + 3 x 4,000K NW LEDs, while the other is composed of 3 x 420nm VL + 3 x 450nm RB. Each LED is equipped with 90 degree optical lens to concentrate the light into the tank. Unlike usual LED lights, the two CR-30 units with rotatable mounting stands make it possible to bring certain lateral light to the tank, leading to an insignificant light shielding resulted from the rockscape. The tank owner is going to have this tank kept with dominant SPS corals and some unique zoa species. The maintenance of such a small tank is understandable in terms of water capacity. Frequent water change as well as the temperature management might be the key points to keep this tank in good condition. Let's just wait and see how this project will be proceeded soon in the near future.
