Large Aquarium Sponge Filter

These aquarium sponge filters are a fine sponge. They collect lots of fine particles and can polish water. I recommend one per 30-40 gallons of water.

I always love buying from the Co-Op because I feel safe knowing that the products are tested and backed by experience.

First sponge filter

I just set this sponge filter up in my 35 gal tank. I am loving it so far the only thing I wish it would have either come with instructions or maybe even a quick video attached to the sales product just because this was my first sponge filter purchase ever and the videos that I have seen on you tube all say to put an air stone inside the filter, but when I took the sponge off there was no space to put a airstone. I figured it out it was pretty easy but I thought I was doing something wrong since I could not get an airstone inside of it. :) Love Aquarium Co-op Crew :)

Could be better

These sponge filters were purchased because of a few videos watched on the subject. When the product arrived, there was no instructions as to how to assemble or use. After working with a few ideas, they were assembled and placed in the aquarium. It looks like they mostly work but for the extra stream of bubbles that are not coming up through the tube. I have yet to see how they work for my tank is new.

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.
