found one at the local lfs for 16 bucks from Marina. looks exactley the same. this one does not come with a pump you will find another use for pump if you buy this one though. i did the opposite instead of going with an air pump I rigged a rio 50 pump. this is a great product all together and flows nicely into my 7.5g cube.using the rio pump to push water into the refugium works great. granted the flow in the tank itself is poor. after many adaptations and trials, I took the air pump and simply added a control valve piece to it and wedged it between the pump and corners of tank. this allows the rio 50 to pick up a little oxygen, if set slightly below or next to it to flow into the refugium. it also causes the surface of the water to break allowing for important oxygen and carbon exchanges as well as keeping the surface clean and preventing buildup on the surface as well. the airstone with pump also causes a slight flow so water circulates is better without buying another pump. Even the smallest circulation pumps in a 7.5g or less causes a massive current. i currently have a lionfish with a few corals in it. he is currently eating the copepods and Amphipods that are in the live rock and coming out of the refugium.
You will need to go to the local lfs or hardware store for an inch long tube to connect the pump to the pipe that runs into the refugium. Also as far as noise and/or water flowing out of the back of the refugium here is a couple suggestions. Take an airline tube and slide it into the pipe just to where it makes its way out of the u bend in the pipe. So about an inch and a half to 2 inches into the pipe. point the tube that is sticking into the refugium down to the bottom. this allows the water NOT to be forced up the sides and out the back. you may also go and just buy the correct tubing to fit over the pipe and point down as well. Also on the gate where the water exits which should come with it. cut out one of the middle bars slide it back in place. I set the gate in so thaat it set where the 2nd bar from the bottom / 3rd bar from top is missing. this will take care of the overflow as well as making sure the feet on refugium are on.
great product and must have. for small tanks.
Buy Finnex External Refugium/Breeder Hang-On Box/Air Pump and Air Tubes, 1-Gallon Now
Using it as a refugium off my sump. I have one of the outputs of the protein skimmer dump into it.I also added the Finnex Might Ray LED, and that is plenty bright to light the box.The airpump set up didn't move much water through it and made alot of noise so I hooked it to a power head. I had to drill some holes to allow a little extra overflow back into the tank. For the money it works great, I have a mangrove plant growing in it.
Want Finnex External Refugium/Breeder Hang-On Box/Air Pump and Air Tubes, 1-Gallon Discount?
I purchased this directly from finnex and have it on the back of a 7.5 gallon Mr aqua low iron reef cube. It fits the back of the tank barely. Water volume is around 1 gallon. If you plan on storing any equipment in this small fuge then the top almost has to be removed as their is no cord room. The fuge fills up almost entirely with hardly any room left. A little shake to the tank causes a slight overflow. The fuge is built so that any overflow will occur forward back into the aquarium. This is done by the back being higher then the front by fractions of inches. I scrapped the air pump and use a hydor pico 180 gph pump. It works perfectly and I get a nice little stream through the fuge with the pump toned back all the way. Full out the fuge overflows, but the flow is much better. Definitely recommend the pico pump if you go with this as a fuge; otherwise the noise will make you purchase one anyway.Save 8% Off
