$250, only 3 months old and in Like New Condition, is a ESHOPPS RS-300 REFUGIUM Sump. Comes with a brand new 7" sock, (2) 3 foot intake hoses, lid and ATO float. Still in the box. I used for 3 months on a FOWLR tank. Pick up in Union county, New Jersey. Retails for $399...
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.
Eshopps R-Series sumps feature unique flow through the separate refugium and skimmer chamber. The main advantage is that your skimmer can now uptake undissolved organics while your refugium can absorb nutrients like ammonia, phosphorus, and other unwanted nutrients without having to compete with each other.
Water Flow
The Eshopps R-Series of sumps has a unique flow pattern. Water first drains into the main drain chamber where a portion of the water will flow into the refugium chamber, and skimmer chamber completely separate. The skimmer compartment has a filter sock to help polish the water of any debris or detritus before entering the protein skimmer, where the refugium compartment gets completely unfiltered water. Keeping the flow paths isolated greatly increases the protein skimmers efficiency and also the growth rate of the refugium. Both chambers drain into the return pump chamber where water can be pushed back into the aquarium by your choice of return pump.
Refugium - 12" x 9.5"
Refugiums are great for holding macroalgae and other nutrient reducing organisms. Just add a refugium light to the R-300 for an efficient source of filtration. Lights like the Kessil H380 is a perfect choice.
Skimmer Chamber - 15.5" x 15.5"
Simply choose any skimmer that has a footprint less than 15.5" x 15.5" and you are in business. The large area lets you choose the best skimmer for your system's needs without having to compromise.
