Eshopps sumps are made out of quality components and let you add additional water volume while giving you more space for filtration and equipment placement. The design of the Refugium series of sumps is simply outstanding. From a drain and return chamber cover, individual flow paths, and ease of maintenance, Eshopps sumps are simply the best.
