How long have you been staring at the Hexa Round Aqua Tower? Seriously, that long? We understand: it gives you spectacular, 360-degree views of your hypnotic paradise, and it's nearly six feet tall! Made from modern, seamless acrylic, it's stronger, safer, and sparkles 40 percent clearer than glass. If you really need to know how long you've been admiring it, opt for the cap that has the beautiful embedded clock with acrylic face and brass hands. Since this unit comes complete with high capacity filter, lighting, long lanky plants, under-gravel filter and air pump, you really don't need to do anything else, besides stare.
