Coralife 14 BioCube Replacement Pump

So far it’s working. A bit high in cost.

Never been more thankful for buying backup products than I am now. I bought a backup pump for my aquarium months ago for precautionary measures because we do not have a store near here that sells aquatic products. A routine partial water change could’ve turned catastrophic for my fish had I not decided to buy a backup pump because mine stopped working out of the blue when I unplugged it for the pwc.I hooked this one up and it works like a charm! I re-ordered ANOTHER pump same day for the future!

Pump is an exact replacement and fits the BioCube 14 perfectly.

Oceanic had the first Biocubes. They were later rebranded as Coralife Biocubes. I have an original, Oceanic Biocube 14, and I can attest to the fact that this pump does not really fit that tank. I can only assume that during the rebranding Coralife changed the dimensions of chamber 3, where the pump goes. If you are familiar with Biocubes, you'll know that at the bottom of chamber 3 there is a short wall that directs water upwards, flowing up from chamber 2. The S700 pump is too long to fit between that short wall and the opposite side of chamber 3. So, you cannot use the suction cups to affix the pump to the tank's floor. You can use the pump, but you have to situate the pump above the short wall. You'll have to shorten the outlet hose, and have the pump suspended from that hose and bulkhead fitting. There is a removable cover over the pump's inlet, but even with the cover removed, the pump is still too big to make it past that wall and sit on the bottom of the tank. Since the pump is floating, you cannot use any of the supplied suction cups to affix the pump to the tank bottom. Be advised, with it floating, you may get some vibrational noise as the pump will be resting against either the short wall, or the back of the bulkhead. Also remember that the higher the pump sits in chamber 3, the better the chance of sucking air if your water level goes too low.

Needed a replacement for the old Biocube. I think this one might be better than the original! Super quiet and fit perfectly. Thanks!

Need to turn off daily for a couple minutes to feed and now you have to bang it around for 5 minutes after plugging back in for it to turn back on. The one that came with the tank never had this issue for the 4 years it lasted.

Perfect fit for biocube led 16 gallon tank. I've been looking for a replacement for months.

Doesn't fit the oceanic without modification. Modified it to fit. Turned it on and its way to loud. Since i modified it, im probably cant send it back. It should be 50 gph more than the original but seems like its moving less not more. So all in all, it way a waste of money.
