    • A gravity vacuum system for a fish tank which will fit onto any standard fish tank and will get rid of waste through a gravitational system. The top of the system is a false bottom for the upper portion of the fish tank. The false bottom features openings small enough to allow the waste to pass. A solid pyramid directly in the middle of the lower one third supports the false bottom. At the right and left foot of the pyramid are drainage valve areas enclosed in boxes. When the drainage valves are opened, the waste flows through the false bottom and into the triangular areas and left of the pyramid. The waste then flows down through the triangular spaces and into the drainage valve areas. The owner then hooks connective tubing to the drainage valves for easy drainage.
    • 用于鱼缸的重力真空系统,适用于任何标准鱼缸,并通过重力系统消除废物。 系统的顶部是鱼缸上部的假底部。 假底部具有足够小的开口以允许废物通过。 直立在下三分之一中间的实心金字塔支撑虚底。 金字塔的右脚和左脚是封闭在箱子中的排水阀区域。 当排水阀打开时,废物流经虚假底部并流入金字塔的三角形区域和左侧。 然后废物通过三角形空间向下流入排水阀区域。 所有者然后将连接管连接到排水阀,以便排水。
