在您家中拥有水族馆应该是一个轻松而宁静的手势。但是，一旦您深入研究礁石，事情就会变得很大。礁石水族馆通常在设备和管道上很重，两者都可以将和平的空间转变为分散注意力的声音音乐会。令人惊讶的是，寻找沉默礁石的集中参考很难。所以让我们在这里做。
The Noisy Overflow:
沉默一个溢出实际上是一个straightforward thing. The most effective way of doing this is using the Herbie and Baggie Method combined. Reef-ready tanks come with two drilled holes. One is usually 1″ and the other 1/2 to 3/4″. The Herbie Method eliminates noise by eliminating air from the drain in the first place. The basic premise is that you utilize both drilled holes in your overflow as standpipe drains. The wider hole will be the main drain.
诀窍是在油底壳之前添加一个闸阀，然后用小1/4英寸的小弯将其关闭，直到水在根直管上方保持1英寸左右，而仍在排水。立管应该足够高，以至于进入溢流的水不必跌得远。较小的立管是您的备份，以防门阀排水堵塞。较小的立管需要高于主要立管。
By utilizing a gate valve to raise the water slightly, you eliminate the noise of bubbles entering your sump. And the taller standpipes will reduce the splash noises, because water will not have far to fall. But even a few inches will cause a noticeable splash. This is where the Baggie method comes into play….
Baggie方法只是需要松散将一些拉链绑在溢流牙齿的顶部。允许将袋子向下坐在溢流中，从而确保溢流水在袋子和内部溢流墙之间延伸。
Both of these methods fall under “TRY AT YOUR OWN RISK”. Ensure that your backup standpipe can handle all the flow from your return pump. And ensure that the bags don’t somehow seal off the overflow teeth.
What about the return? Now that the return pump bulkhead has been repurposed as a backup drain, the return pump plumbing requires a little more DIY. It’s not that hard to just plumb it over the lip of the tank.
Loud equipment:
这个更容易在新版本上修复，因为购买合适的装备是赢得噪音战的90％。主要罪魁祸首是泵，撇渣器和冷却风扇。
首先，内部泵和撇油器通常更安静。远离大声的野兽，例如魔术驱动器。基于Askol的泵以其沉默而闻名。Sicce和Tunze也保持沉默。确保您的撇渣器和返回泵属于这些类别的品牌。要使现有的返回泵安静下来，请在当地的厨房商店寻找硅胶方锅夹具。它们是放置在泵下以减少振动噪声的理想选择。
稀薄的橡胶振动垫可以通过汽车音频供应商以及洗衣机打击器来采购。在您的水底和水族馆支架之间添加这样的垫子将进一步减少振动嗡嗡声。而且，如果您是硬PVC管道的粉丝，请确保在PVC和您的返回泵之间包括一小部分乙烯基或硅软管。这也将减少振动。
大多数水族馆的支架都在背面敞开。这是减少污水和相关过滤潜在的湿度问题的一件好事。一些人选择用胶合板（密封和涂漆）将其关闭，并使用小型计算机风扇去除陈旧的空气。封闭看台可以使噪音保持内部。当您使用时，用薄的闭孔泡沫将支架的内侧和门排列。它也很容易从汽车音频场所采购。老实说，如果您明智地选择设备，那么隔音可能会过大。
Loud fans are tricky. If the fans are in a name-brand light fixture, you should not mess with them unless you have some electrical background. And you are probably risking the warranty as well. Ultimately, it’s probably smarter to look for a better designed fixture. If it’s canopy fans in question, there are many really quiet computer fans available these days which work great for canopy cooling as well.
Noise, especially vibrational hum, can be extremely distracting from a beautiful reef tank. Good planning and a little DIY can eliminate the noise and bring the focus back on the fish and coral. If you have any additional noise reduction tips, we’d love to hear about them in the comments or the reefbuilder forum!
