摘要： An aquarium overflow filter system having a pre-overflow wall with openings therein improves circulation of water throughout the aquarium tank. The overflow filter system includes an overflow wall that separates the tank into a main aquarium region and a filter intake region. An intake for a wet/dry filter is located within the filter intake region. A pre-overflow wall located outside of the filter intake region encases at least part of the overflow wall to create a mixing chamber therebetween. Openings in the pre-overflow wall allow water to flow through the pre-overflow wall into the mixing chamber. The openings in the pre-overflow wall can be strategically placed to attain a desired circulation pattern within the aquarium. Water pressure at lower openings in the pre-overflow wall tends to move water upward through the mixing chamber, thus water from all the openings eventually flows over the top of the overflow wall into the filter intake region. The invention can be used to improve filtration circulation and the ability to pick up suspended debris off the bottom of the tank. The invention can also provide more natural flow patterns throughout the aquarium.
摘要翻译：具有其中具有开口的预溢出壁的水族箱溢流过滤器系统改善了水通过整个水族箱的循环。溢流过滤器系统包括溢流壁，其将罐分离成主水族箱区域和过滤器进入区域。用于湿/干式过滤器的入口位于过滤器进入区域内。位于过滤器入口区域外部的预溢出壁包围溢流壁的至少一部分以在其间形成混合室。在预溢出壁内的开口允许水通过预溢流壁流入混合室。可以有策略地放置预溢流壁中的开口以在水族箱内达到所需的循环模式。在预溢出壁下方的开口处的水压倾向于将水向上移动通过混合室，因此来自所有开口的水最终流过溢流壁的顶部进入过滤器进入区域。本发明可用于改善过滤循环以及从罐底吸取悬浮碎屑的能力。本发明还可以在整个水族箱中提供更自然的流动模式。
