Why do I want a sump?
* Increased total water volume - This dilutes your water of accumulating pollutants, and helps avoid issues that occur quickly in sumpless tanks.
* Skims the surface - No more surface scum, just crystal clear water.
* Hides equipment - Heaters, protein skimmers, monitoring probes, and more can be moved to the sump & out of the display tank.
* Consistent water level - The display tank will maintain the same water level all the times; evaporation occurs in the sump over time
* Safe place to pour in additives - Adding chemicals or new RO water in the sump allows it to mix before entering the display tank.
* Increased circulation - The return water from the sump is yet another way to move water in your tank. You can point the return outlet(s) in different directions to create flow, instead of putting more powerheads in your display tank!
* Increased oxygenation - As water drains into your sump, air mixes in the water, allowing beneficial gas exchange, releasing CO2 and adding fresh O2.
