Live Arrival Guarantee
We guarantee our live products will arrive alive. We ask that you do your part and minimize the amount of time our packages sit out in the elements. It can also be a good idea to avoid ordering live items during extreme temperatures. This would be when night time temps are below 35 and over 80 degrees during the day. Now these temps are not for sure death, it's just what makes it easiest for all of us during shipping.

When temperatures are cold we will use heat packs and extreme cold styrofoam liners. Shipping live goods is difficult as our warehouse could be 70 degrees and your home could be snowing, and all the stops in between. We do our best and will make it right for you and may request to try again at a different time.  During heat waves, it's best to avoid ordering live goods as ice packs etc don't do enough to mitigate it. 

30 Day Return Policy
Our goal is to provide a fair way to satisfy our customers and not lose money while doing it. We make every effort to fully disclose how our products work and what is to be expected. A damaged product during shipping is an automatic replacement from us. When it comes to a difference of opinion such as: "My fish doesn’t like this food." That we don’t refund for. However, if you decide the light you bought is a bit too green for your liking, provided it is in the original box, within 30 days and purchased from us, we will refund it at your cost of shipping.

If you would like to return a product, start the process by emailing us at shipping@aquariumcoop.com This allows us to see if there is something we can do before returning the product such as a feature you didn’t know about or send you a return label. We don’t require an RMA number, but do ask you to contact us to initiate the return. Please do not call the retail store as they operate separately from the warehouse and will not be able to issue you a return label etc.

Cobalt powerhead

I think the cobalt power head is my favorite. Done with the RIO units. They are flimsy and fall apart just by handling them in the tank.

Great for speeding up water changes

I have a 125 gallon discus tank where I change 40-80% of the water each day. I have a 44 gallon trash can that I age my water in and with this little thing along with some rubber hosing from Home Depot it speeds up the process like no other. Great power head and I've not seen any issues with it yet.

Versatile reliable

I am using this powered in a large cichlid tank. I have it running a diy sponge filter. Works great picks up a lot of fines from the water and adds just the right amount of circulation. Very strong and reliable.
