I went to to jeju island in Korea. Jeju is most beautiful region in Korea and I visit here with my family every year. Recently Beautiful and huge aquarium is opened in here so I visited there with my family. We do not have to visit Churaumi Aquarium at Okinawa in Japan for seeing Whale Shark.
This was one of my amazing experience and scene that I had. In Korea, You can see the whale shark in Jeju Island. Visit Here~!!
[Update 2012.8.07] Recentely There is some renewal of Mr Kang's houuse. Because He should move and aquascape his tank, Aquascaping is updated. And still beautiful.
[Update 2012.3.26] Happily Mr Kang's Tank is introduced at AA online in Facebook and many people wondered his rockwork. So I asked him to show more pic for us and He give me some good photos. Thanks for sharing~!

그래서 오늘 Leonardo의 새로운 어항을 소개하고자 합니다. Leonardo가 깔끔하게 정리해준 덕분에 저는 그냥 Copy &Paste만 하면 되겠네요. 새어항이라 깔끔해보이기도 하지만 Layout자체가 독특하고 깔끔해 보입니다. 그가 붙인 어항의 Theme은 Apogon Reef입니다. Leonaro는 Apogon즉 Cardinal fish를 매우 좋아하는 Reefer입니다.
군영을 이루는것처럼 보이는 크로미스류는 실제로는 군영이라기 보다는 군영과 견제가 계속해서 이루어지고 있어 한정된 공간에서는 소수의 크로미스류만이 남는 경우가 많습니다만 Apagon류는 실제 군영이라는 것을 계속 하고 있기 때문에 여러마리가 같이 있는 경우 꽤나 멋진 View를 보여줍니다. 사진의 Apogon Leptacanthus를 60마리,Apogon Margaritophorus를 20마리정도까지 넣을 예정이라고 하니 이후에는 훨씬 더 멋진 View가 연출되리라 기대가 됩니다.
Leonardo가 보내준 자신의 어항 스펙 및 세부 정보는 다음과 같습니다. 그의 어항도 계속 업데이트를 진행할 예정이며, 궁금하신점이 있으시면 댓글로 남겨주세요. 제가 물어보고 답변을 드리도록 하겠습니다. ------------------------------------------------------------------------ Aquarium Profile: I've been absent for a while, mainly because of moving to another apartment and starting a new job. Almost a year ago I started with a new idea. A reeftank with many Apogon species hiding in and between large Acropora Colonies. The whole year I spent collecting Acropora Colonies and Frags, aquascaping the tank, but I was never satisfied. I even thought of getting out of the hobby, it just didn't gave me satisfaction anymore and I could not be happy with the results I was getting. But I kept trying and at last I have something now I'm (slightly) pleased with, although I'm far from where I want to be. From this moment I would like to share the progress of the tank with you guys and I would really like your input and ideas. The new tank -Apogon Reef- will be Apogon dominated. That means +75 Apogons, several species. Not too many, large Acropora will provide shelter for the very high flow (2x 6301) The Apogons (and the corals indirectly) will be fed from dusk till dawn with many automated feedings in small amounts, to mimic their natural feeding pattern.
A BB tank allows me to use high flow, heavy feeding and direct nutrient control.
Hardware: 10 x 39 Watt T5 using ATI Sunpower Pendants LED Supplement (CREE XP-E Royal Blue and Blue) 2x Tunze 6301 on multicontroller Eheim 1262 Return Pump Grotech TEC III Controller for Balling+ Trace Elements D&D Fluidized Reactor for GAC and GFO I chose to use many T5's on the blue end of the spectrum because of the large amount of deep water Acropora tables. These seem to adapt better the light in the blue end of the spectrum:
5x ATI Blue+ 2x ATI Purple Plus 2x Red Sea True Actinic 1x ATI AquaBlueSpecial Bubble King SuperMarine 250
(Future) Livestock: 60 Apogon Leptacanthus 20 Apogon Margaritophorus 1 Pseudocheilinus Hexataenia 1 Salarias Fasciatus 1 Acanthurus Triostegus 3 Halichoeres Chrysus Some other fish may be added later on. For example some Wrasse species.
Watercirculation: I think water circulation is the most important thing in a reef tank system. Most importantly it provides oxygen to all living organisms. Besides that it keeps the detrius suspended in the watercolumn, creating a valuable foodsource for sponges, tunicates, featherdusters, and -of course- the corals. It also gives you control in the amount of detritus that will be skimmed off, but later more about that. The flow is provided by 2 Tunze 6301 pumps, pulsing 30-50% every 8 seconds, creating a random flow throughout the tank. The Eheim Eheim 1262 returnpump also creates a good amount of flow.
Filtration and Equipment: The skimmer that I use in this tank is a Bubble King Supermarine 250 internal. Once you have ajusted it, you only have to clean the collection cup every 2 to 3 days. I ajusted the skimmer this way; I found a balance between nutrients/algae and healty/fed corals. The skimmer now skims semi-dry; It removes the organics fast enough to prevent phosphate/nitrate elevation, but not too fast to starve the corals in this Bare-Bottom system. I have a Fluidised bed reactor that is placed in the sump. I always use a small amount of Granular Ferric Oxide and Granular Activated Carbon, to make sure the Phosphates and organics remain unmeasurable. When algaegrowth on the glass increases, I know it’s time to replace the GFO. Usually I replace it every 2 weeks. At the same time I replace the GAC. The large return-pump helps me to circulate fresh skimmed/filtered/oxigenated water and tankwater fast, creating a healthy envirionment in the tank. It also prevent detritus from collecting in the sump. Four computer fans helps me to keep the temperature around 79 Farenheit - 26 degrees celcius. A Grotech TEC III 3-channel dosing pump is used for automated 2-part dosing (balling-method) and automated dosing of trace elements.
Maintenance: The daily maintenance consist of checking the equipment, temperature, and feeding/checking the inhabitants. I check if all the inhabinats are there, and make sure their behaviour is normal. I clean the skimmer when the cup is full, every 2-3 days. Cleaning of the glass is also done every 2-3 days. Topp-off is done by hand every day. Every 2 weeks I do a 30 Gallon Waterchange with D&D H2Ocean salt. The skimmer is taken out and completely cleaned once a month.
Feeding: I feed a lot, because I think you have to feed not only the fish, but the whole tank indirectly. That’s why I think diverse, high quality food is important for the reeftank to be diverse and healty. With the heavy flow, large skimmer and GFO I feel safe enough to feed a lot. The fish are fed 2-3 times daily with small amounts of food. 2 times dry food, and one time frozen food. I vary with the food from day to day, to create some alternation. Food: O.S.I.

추가적인 스펙이 공개되었습니다. 10K 버젼과 16K 버젼으로 나뉘어 나오는 것 같고요. LED에 대한 지식이 많지 않아서 Reefbuilder에서 나온 이미지정도만 간단히 링크 하도록 하겠습니다.
LED fixture에 대한 구성은 Mazzara와 유사하다고 적혀 있네요.
Most of the features of the Razor follow along with the Mazara X that came before it; a built-in controller, dual channel control, six time points per channel to set your lighting schedule, etc… That’s where the similarities end though. As we touched on before in our first announcement of the Razor, gone is the ability to individually replace LEDs as the end user sees fit.
저는 일주일에 10%(40리터)정도의 물갈이를 진행합니다. 한국은 소금이 무척이나 비싸기 때문에 괜찮은 브랜드의 상대적으로 싼 소금을 구입하려고 하는데요. 최근에 사용했던 브라이트웰 소금은 이상하게 물갈이를 위해 소금을 녹였을 때 물이 뿌옇게 되는 현상이 일어납니다. 카보네이트가 나오는 것 같은데요.. CO2의 영향도 있을 수 있고 삼투압때문일 수도 있을 것 같아 이것저것 환경을 바꿔보았습니다만 결과는 비슷했습니다.
마그네슘을 현재는 물갈이에만 의존하고 있기도 하고 칼륨이 상대적으로 높은 비싼 프라이스 소금으로 바꾸었는데요.
6만원 이상의 값을 더 주고 사야 하는 소금이긴 합니다만 녹은 소금을 보니 물이 깨끗하게 잘 녹아 있습니다. 보기에는 입자가 더 굵어보이고 싼 소금처럼 보입니다만 RBS포함 2번째로 한국에서 비싼 소금입니다...
IO 같은 소금도 외국에서는 많이 사용하고 있습니다만 적절한 칼륨공급과 안정적인 수치를 제가 부지런히 맞출 수 있을런지는 의문입니다. 부지런하지 못하면 돈이 더 드는 것 같습니다.. 아래의 사진은 브라이트웰 통안에 넣은 프라이스 소금입니다. ㅎㅎㅎ
