Brand new Eshopps AF-100 sump. Bought this for a build then plans changed. Came out of shipping box once, never touched by water.

The Alpha-Fuge sumps are designed for the advanced hobbyist, incorporating Eshopps’ unique Triple Water Channel Design and an easy access filter sock with a clear removable lid. The Alpha-Fuge Refugium Sump features a large protein skimmer compartment with dosing tube and a probe holder cradles. In addition, Alpha-Fuge sumps feature a large return pump compartment with built in water level ATO float valve and a hang on multi-purpose media tray. The media tray can be used as an in-sump passive media filter. Additionally, the refugium compartment has a removable algae blocker panel along with a built-in bubble trap with easy change filter sponge. The Alpha-Fuge is designed to meet all the demands an advanced hobbyist can dream of.
