The two photos show the latest condition of the 5.8ft long display tank in Ming-Chen shop of NKAC. As one can see from the photos, the rockscape of this tank is simple but unique. Unlike some reef tanks which are full of rocks, the designer used limited rocks to construct an aquarium space for dominant LPS and soft corals. It's really a masterpiece! We are also happy to see that all corals are in good condition.
Remember the lighting system composed of 6 x CR-60 units that we introduced last week? The photos below show the tank which adopts this lighting system. The dimension of this newly built tank is 75cm x 75cm x 42cm. The owner of this tank is a reefer who has serveral years experience on keeping SPS corals. He used to believe that SPS corals could only grow and display the best under the illumination of metal halide and/or T5 lamps. However, the high power consumption of the traditional lighting fixtures has made him to re-consider the lighting source when he decided to build a new SPS-dominant tank about three months ago. After seeing our ComboRay series products from pH8.4 forum, he realised that this new products might be a possible candidate to replace his traditional lighting system. He dicussed a lot with us on how he plan to set up the tank and the rockscape for this new tank. He was also interested in testing the fesibility of using only LED lights on growing SPS corals. We helped him to install the whole lighting system on last Saturday. According to him, the light brightness is about the same level of the old 2 x 250W metal halide lamps judged by naked eyes. He was also suprised with the effect of the actinic lights that we suggested (400nm+420nm+450nm LEDs). We are quite exciting about the future of this tank. More SPS will be brought into this tank soon. We will keep you posted with the latest condition of this tank in the coming future.
The two photos above show a lighting system composed of 6 x CR-60 units. As one can see from the colors of the LEDs distributing within the six units, two main layouts were adopted in this system. One is for actinic lighting which is composed of 400nm/420nm/450nm LEDs. The other is for white lighting which is composed of 470nm/500nm/7000K/4000K LEDs. The customer who bought this system plans to use this lighting system on his new 75cm x 75cm x 45cm tank with dominant SPS corals. We are confident with the "quality" of the light since the light is composed of wavelengths ranging from 390nm to 700nm. With regard to the light intensity (or penetration), we have added 60 degree optical lenses on each LEDs except for the 400nm Near-UV and 500nm Cyan LEDs. With the 60 degree lenses, the light generated from a 2W LED will be as bright as that from a 5W LED. There should be no problem with the light on covering such a wide area since the whole lighting system is about 50cm wide and 55cm long. This lighting system will be installed by the customer this weekend. More photos will be available soon. We will keep you guys posted with the latest condition of the tank here in the future!
