First and foremost I must remind you that this pump is not submerged. This means you will need to get the pump and its tubing full of water before activating it. This can be quite a difficult task if you are not willing to suck on the tube. I personally use a different pump to prime this one, then remove the secondary pump.
As the pump is not submerged it will also be more audible than most pumps. It is by no means loud, but you will no doubt hear it.
The power cord on this pump measures a decent 6 feet, while the nozzles will are designed for 5/8" ID tubing. They will accept 1/2" ID tubing as well. There are locking rings to help keep the connection in place, which takes most of the worries away from an inline pump.
The Cobalt inline aquarium pump has four suction cups on the bottom of the pump, which lets you secure the pump to any flat surface. This is helpful for keeping the tube in place, however it increased the volume on my set-up. The pump is fine to hang free, so long as the tubing supports it.
This brings us to the most important part of set-up. Plumbing, no matter how simple the set-up, should never be taken lightly. Ensure all of your tubing is connected firmly and will not slide over the years it will be used. If I can pull off my tube with a slow, weak pull then I will not trust it with even a 40 gallon water column. Likewise ensure that the end of the tube will stay in place when the pumps are on. My first set up was a tube hanging into the tank with a PVC L pipe holding it in place with only its body as support. As dumb an idea as that was it still worked for years. I'm just lucky it never fell off and flooded the upstairs room it was in. It could have caused hundreds of thousands in damages! Cobalt offers a hearty 3 year warranty on this pump, making it one of the longest protected aquarium pumps out there. you will need to call their customer support listed on the bottom of their .
When used properly, with no dry running and once a month cleaning owners will often see a lifetime of up to 6 years. Their products are produced in Italy, removing the chance for poor Chinese construction that many other products have. Should the pump fail within the first three years and be replaced, you would actually get a better lifetime than most owners. Remember the impeller is the main component that gets damaged, and this is either from too much tubing or running the pump dry. Avoid those two and the Cobalt Inline pump can work wonders. When disassembling and reassembling the Cobalt inline pump you will be handling the intake valve.
First you will need to unscrew the compression nut(1) and impeller housing(2). After this you will be able to remove the impeller(4) along with its shaft(5).
The impeller and shaft should be cleaned by soaking a 50/50 mix of water and distilled vinegar, followed by wiping them off with a soft material.
While the two parts are soaking you can clean out the pumps housing and the connected tubing. Remember not to use any chemicals and only scrub them clean with materials that have not been used for anything but aquarium handling.
Rinse off the impeller and shaft before reassembling the pump in reverse order. Run the pump while submerged to ensure it is working properly before setting it back up. External Aquarium Water Pumps consist of an external motor which pulls water from the aquarium or sump and pushes it out the outlet. This is the most common type of water pump for an advanced freshwater, marine and reef aquariums. External water pumps are more powerful than submersible pumps and help keep the heat out of the water. Commonly used as return pumps to feed filter water back to the aquarium and to drive aquarium equipment such as canister filters, protein skimmers, uv sterilizers and specialty filters. External water pumps are usually installed at the floor level next to the sump. External (in-line) pumps are recommended for larger aquariums 100 gal or more in volume. External water pumps will usually give you higher pressure and flow but may be a little louder comparing to submersible pumps.
