Nano Tank Hang on Back Filter

This filter is very quiet, easy-to-use and clean!

This thing makes no noise if the lid is off. I love that it came with a pre filter. I have been using this between some nano tanks with a bunch of filter floss to help clear up my water. I am not using it as a primary filter although it is tempting

I have a 6 gallon cube that this worked perfect on. Super quiet. Looks great and customizable. I hot rodded it by using the Co-op course filter pad.

I love this filter (I have a couple) and how easy it is to customize. Cleaning is easy with a little brush for the intake tubes. I got rid of the cartridges and replaced with a block of coarse sponge as well as well as an additional foam pad. As long as it's full of water, it's a quiet as they come.

This little filter works great in my 6g planted betta cube. I love that I can take it almost completely apart to clean it with a little bottle brush. I replaced the cartridge with coarse sponges and a handful of bio rings. Very quiet if the water level is topped off. Mr. Nakatomi is happy.

I'm new to fish keeping and wanted something easy and safe for my first tank. After doing some research, I found aquarium co-ops videos and decided to order this filter(and the upgraded sponges). Works great in my 5.5 gallon, though for my betta I had to put the flow to the least it could be. Overall though, it's pretty quiet by my standards, and it's a great filter!

I received this sponge filter today and it’s running quietly! I’m 79 and live alone and recently bough a beta fish and all the accessories required. I’ve always wanted a sponge filter for my 5 gallon tank, and the instructions were simple enough that I could get this installed own! I consider that a miracle!
I wanted a planted aquarium and I have been ordering all of my plants from aquarium coop.
I had ordered a filter from a large company in China. It came without instructions and it was very confusing. I immediately returned it!
Aquarium Co-op is wonderful!

It was packaged nicely, and came with a STCIKER! The filter itself was easy to set up. I love the adjustable flow. It’s also very quiet! The filter lid makes a tiny bit of noise but it not noticeable among my other filters and humming sounds XD I’ll definitely be buying from here again!

I have a 5g aqueon mini bow and wasn't too fond of the filter in it so I took it out and put this nano hob in and I like it! Wasn't sure about some things and contacted customer service and candi responded asap and helped me out. So wonderful. The box said self priming but had to initially fill it up with water to get it started. And managed to get in the course sponge(cut the thickness in half) polishing pad and my bag of matrix. Awesome. Love that it has adjustable flow. I have it on low which is alot more than how the aqueon filter was which is great. I just wish the extra aco nano pre filter sponge I had fit good on the intake it was too loose so I use the one that came in the box for now. So this was another great buy from aquarium co op I'm happy with it.

I've been having issues trying to find a pump that was Betta friendly. I got a new 5 gal tank but the pump was too strong for my Betta. I used sponges and zip ties in the discharge, would usually create more issues than solutions. Saw Aquarium Coop on you tube and as soon as I saw this pump, I had to have it. It's been nothing but excellent. Better filteration and the adjustable flow control. Now I've got a happy Betta that swims all over his tank and doesn't spend his days hiding from the pumps discharge. Love this thing!
