如果你以为lighting for Joe Yaiullo’s 20,000 gallon reef tankis eclectic, just wait until you get a load of the various filtration devices that are employed on this behemoth reef aquarium display. From filtration devices, to protein skimmers to various types of chemical medias, the 20K reef tank at Long Island Aquarium employs the whole gamut of different techniques to keep the water clean and clear, healthy and presentable.
By far the best and largest single device that is in use on the giant reef tank is a huge protein skimmer that Joe built himself, with very simple venturi injection protein skimming principles, same as what you might expect on a skimmer from nearly 20 years ago, except scaled up to humongous proportions. We don’t have exact specs on the multi horsepower pumps in use on this aquarium, or how much air draw this protein skimmer sucks in, but we did take a look at the collection cup and the giant heaping mound of skimmate is all we really need to know about this skimmer’s everyday performance.
也是在最大的礁石罐中使用的，这是一种很好的O3臭氧，这是一种与文丘里注射撇渣器特别有效的技术。在这个储罐上，由4细胞Eclipse4 O3发电机每小时添加1000毫克的臭氧 - 我们喜欢与Joe谈论他的Eclipse 4的一件事是他对O3生成细胞执行的常规维护，以及执行预防性的重要性对这样的设备和其他设备进行维护，以使其处于高峰工作状态。臭氧确实有助于清除水族馆的水，尤其是在如此沉重的鱼负荷下，乔可以判断臭氧是否没有正确地伸入他的脱毛器，因为坦克会在三天内开始向水显示黄色的变色。
You might be surprised to learn that this is not the end of the 20K reef’s protein-skimmer related filtration duties. As if the homebuilt venturi and the heavy duty ozone administration wasn’t enough, there’s also其他protein skimmer in use, a large dual 6ft ETS downdraft skimmer which is there for redundancy, and also to serve as a more dedicated vodka dosing location. Of course the addition of Vodka to the tank, somewhere around 250ml per day, is experienced throughout the entire aquarium but by using both the super dry skimming of venturi, and the wetter skimming of downdraft skimming, Joe can really suck out the wastes accumulated by bacteria feeding on the liquid carbon from the Vodka ethanol.
The Vodka / liquid carbon dosing regime is only one of the many techniques that Joe uses to combat nutrients in this very big reef tank.The heavy lifting of removing phosphate is performed by generous additions of Lanthanum Chloride, a common chemical additives for use in swimming pools that is excellent at binding and precipitating PO4.
但是，LACL的使用只能降低到目前为止的PO4水平，这是去除磷酸盐介质可以使磷酸盐水平进一步下降的地方。除了使用大量Phosban GFO的典型介质反应堆外，Deltec还有另一种专门的介质反应器，Deltec是一种6英尺高的塔楼，专门设计用于流化的介质，目前正在使用Blue Life USA吸收的高容量磷酸盐吸收树脂。
The final aspect of the ‘filtration’ used in this ginormous reef aquarium mesocosm is a home-built dual-chambver calcium reactor that is powered by two blueline pumps, one for each chamber. The Heavy duty calcium reactor design is mighty useful for keeping up the alkalinity, but Joe also doses加仑卡尔瓦瑟（Kalkwasser）也是礁石坦克（Reef Tank）。Kalkwasser与少量醋混合，以添加钙溶解，并缓冲完全饱和氢氧化钙的极高的pH值。
