  • Adjustable flow control knob 
  • Excellent for small aquariums under 10 gallons
  • Great betta tank filter

This nano hang-on-back filter is excellent for aquariums up to 10 gallons. It moves 52 gallons per hour and has an adjustable flow knob for fish who need lower flow such as bettas. It comes fully equipped with media and an intake sponge. However, upgrading to our mini pre filter sponge is ideal as it offers greater coverage of the intake tube with less clogging from debris. Hot rod this filter by adding coarse sponge to the media portion rather than the provided cartridges.

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.

Perfect for betta, nice and quiet!

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!

Wonderful 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!

Perfect filter for my 5.5 gal!

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!

Great upgrade

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.
