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.

Wonderful

I never realized how much my hob filter sucked up. No wonder I went through so many filters. This filter pulls all the trash and uneaten food to it. My fish, shrimp , pleco love cleaning the filter. I have used under gravel filter for years. NO MORE. LOVE that it's permanent and you just clean them with aquarium water as you replenish the tank. Works well in my 40 gallon tank. VERY satisfied. Great service, quick shipping. Love your you tube channel. Thanks for an overall positive experience. Ordered live plants today.

Great

I love these things. They really do polish the water, and I figure if I am going to run an airstone of some sort anyway, why not have it also filter the water while I am at it? I do make a bit of a modification to my sponge filters by cutting out most of the center material in the plastic inside the sponge. I then add a fine bubble air stone to the air line and run it that way. You have to leave a few of the spokes at the bottom longer when you cut them so it will hold your air stone in there, but it completely eliminates the glug glug noise and still works fine to pull water through.

Work horse sponge

I have either sponge filters or Fluval HOBs in all my tanks. As always, the tanks take a while to cycle, but with the sponge, once they've cycled, I have beautiful water and healthy fish. What more could one ask for? Grateful to Cory and the gang for bringing this new hobbyist into the fold. Never knew I needed fish...but I guess I do! :)

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.
