Description of decorations: The substrate is fibrous peat on it fine sand from the river covered with a large amount of decaying leaves and peat. The roots used for decoration come from peat bogs. The appearance of my aquarium of the black waters of South America, despite the constant decor, is variable. By periodically adding leaves and peat, its appearance changes every few weeks, additionally the light operating in 24h mode causes that our underwater world can still delight us.
装饰描述：底床为纤维状泥炭，其上覆盖着来自河流的细沙，并铺有大量腐烂的叶片和泥炭。用于造景的树根取自泥炭沼泽。尽管造景元素固定不变，但我这座模拟南美洲黑水的水族箱外观却时常变化。通过定期添加叶片和泥炭，其面貌每隔几周便会焕然一新；此外，灯具以 24 小时模式运行，让我们的水下世界持续展现迷人风采。
Description of equipment: The Hamburg filter is located in the rear of the aquarium and is powered by the aquael 500 circulator, which is set to minimum efficiency. The lighting consists of a 150 W radiator. The lighting consists of 0.75W LED modules each: 4x3000K, 4x8000K, 2x blue and 5x11000K, controlled by dawn controller – twilight TC 421, which gives the possibility to use 5 channels (sections) which also I did.
设备描述：汉堡式过滤器位于水族箱后部，由一台调至最低效率的 Aquael 500 循环泵驱动。照明系统包含一个 150 W 的灯体，由多个 0.75 W 的 LED 模块组成：4 个 3000K、4 个 8000K、2 个蓝光模块以及 5 个 11000K 模块，并通过黎明–黄昏控制器 TC 421 进行控制；该控制器支持 5 个通道（区段），我也已充分利用了这一功能。
Water parameters: The water temperature is 25 ° C, the water color can be compared to the tea color pH 5.6, KH and GH unmeasurable, TDS 36 ppm.
水质参数：水温为 25 °C，水色可比拟茶汤颜色，pH 值为 5.6，KH 与 GH 无法测出，TDS 为 36 ppm。
Additional info: This is the continuation of “Small Creek in the Rio Negro system, Amazonas state, Brazil” from the previous year’s contest. The arrangement was changed, and I left only the small schools of Paracheirodon axelrodi, recently the male Apistogramma agassizi entered the cast due to the spawning he had just carried out (previous spawning was eaten by him) and I had to move him to another tank.
附加信息：这是去年比赛作品“巴西亚马孙州内格罗河水系中的小溪流”的延续。布景有所调整，我只保留了少量阿氏霓虹脂鲤（Paracheirodon axelrodi）的小群；最近，一只雄性阿氏短鲷（Apistogramma agassizi）因刚完成产卵而加入其中（此前的鱼卵被其吞食），我不得不将其移至另一水族箱。
INFORMATION ABOUT BIOTOPE
关于生物群落的信息
Description of the area surrounding the biotope: Black water of South America is primarily a landscape of sand covered with tangles of roots, leaves, algae and fish perfectly adapted to this difficult environment. The water is tea color, barren and very sour. They are part of the great Amazonian basin water system.
生物栖息地周边环境描述：南美洲的黑水景观主要由覆盖着盘根错节的树根、落叶、藻类以及完美适应此严苛环境的鱼类所构成的沙质河床组成。水体呈茶色，贫瘠且酸性极强。它们属于广阔的亚马逊流域水系的一部分。
The forest surrounding this small river reflects many organic substances. These are primarily leaves and fruits falling from trees and rinsed during the rainy season, as well as roots and broken branches. They rot and give off tannins and humic acids – substances that strongly acidify and color brown water. The bottom of the water reservoirs is usually sandy but covered with a thick (20-30 cm) layer of rotting plant particles. There is a lot of decayed wood in the water. The biotope of black waters includes both running and standing tanks. The first of these is usually slowly flowing river. These include, for example, Rio Negro, Rio Cururu, Rio Arapiuns, Rio Tefe and their tributaries. Black water also occurs in bays and small storages surrounded by jungle.
环绕这条小河的森林释放出大量有机物质。这些物质主要是雨季期间从树上掉落并被雨水冲刷的树叶和果实，以及树根和断裂的树枝。它们腐烂后释放出单宁酸和腐殖酸——这些物质会使水体显著酸化并呈现褐色。水库底部通常为沙质，但覆盖着一层厚达 20 至 30 厘米的腐烂植物碎屑。水中还存在大量腐朽木材。黑水生物群落既包括流动水体，也包括静水水体。前者通常是流速缓慢的河流，例如内格罗河（Rio Negro）、库鲁鲁河（Rio Cururu）、阿拉皮恩斯河（Rio Arapiuns）、特费河（Rio Tefe）及其支流。黑水也出现在被丛林环绕的海湾和小型蓄水区中。
Description of the underwater landscape of the biotope: Small Igrape belonging to the black waters of the Rio Negro basin near Barcelos do Rio Negro, Dept. Amazonas near 63.04’W / 0.01’S, sometimes referred to by local inhabitants of Rio Salgado. There are a lot of trees, the roots of the leaves, and the fruits cover the bottom of the tank, giving the fish plenty of hiding places and food.
该生物群落的水下景观描述：位于巴西亚马逊州巴瑟洛斯（Barcelos do Rio Negro）附近、内格罗河流域黑水区的一条名为伊格拉佩（Igrape）的小溪，地理坐标约为西经 63.04°、南纬 0.01°，当地居民有时也称其为萨尔加多河（Rio Salgado）。此处树木繁茂，树根、落叶和果实覆盖了水底，为鱼类提供了丰富的藏身之处和食物来源。
Description of the parameters of the habitat: The light entering the water is limited by branches of trees growing on the shore. The color of the water give the tannins is dark brown and very transparent up to 3 meters. The water is acid and barren. The average temperature in the rainy season is 23 ° C and lasts from September to May, the pH is 6. The remaining months are dry season and the average temperature is between 28-30 ° C, while the pH is very acidic up to 3.5.
栖息地参数描述：岸边生长的树木枝条限制了进入水中的光线。水中单宁酸使水色呈深褐色，透明度可达 3 米。水质呈酸性且贫瘠。雨季（9 月至次年 5 月）平均水温为 23°C，pH 值为 6；其余月份为旱季，平均水温介于 28–30°C，pH 值则极度偏酸，可低至 3.5。
