Hang on back overflows do require more monitoring and safety precautions to be in place, but can be completely reliable if installed properly and maintained regularly.Installation only takes a couple of minutes, and the PF-1000 only requires 3″ of clearance outside the tank to drain water down to a sump, refugium, or wet/dry filter. Just lower the overflow box onto your aquarium and then connect your favorite type of plumbing to the included 1″ bulkheads.Specifications:Item #ModelDimensionsTank usage10100PF-Nano4″x2.5″x8″10-20g Nano11000PF-3006″x3″x10″30-75g Single11005PF-8008″x3″x10″75-125g Single11010PF-10009″x3″x10″125-150g Dual11015PF-120010″x3″x10″150-200g Dual11020PF-180012″x4″x10″200-300g Dual
