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.

Invertebrate safe!

I bought this to keep my anemones safe. Its works great!. My banded coral shrimp loves it to. I often find him resting upside down on the bottom.

Best I've found

I've been watching Cory for a few months now. I've taken quite a few of his tips, and enjoy his content. This pre-filter is perfect. Much better than any of the others that I've found locally. I wish his store was in my area.

Great investment

Works like a charm filtering floating leaves in my planted tank. Plus it serves as another place to keep good bacteria.

Makes a huge difference

My husband and I were frustrated by having to constantly clean off debris from the intake. We watched Cory's video on the benefits of putting a pre-filter sponge on the intake and decided to try it. What a difference! Within the first day we could see the larger pieces of debris on the sponge. We both highly recommend this product. Thanks again Cory!
