Works well, although you need to be careful when putting it together filling with water as it can leak if not totally pushed down firmly before applying the 4 little lid locks. The hose supplies is barely adequate length. I have a 60cm tank on a stand and the hoses were too short. Fortunately any hardware store has this hose size cheap. All up a 3.5 out of 5 Stars for my rating.

Great desktop canister filter for my desktop aquarium. The filter is a little noisy in the middle of night. You would have to be in the same room to hear it though. Otherwise I am very happy with it, it circulates the water around the tank really well.

Good filter but the length of the hoses are a joke. Way too short to be of any use without grabbing extra ones. Contacted Aqua One and they were less than helpful.

Works great should have gone with a canister filter straight up
This filter exceeded my expectations for the price range. It's absurdly easy to set up and get going. It almost takes longer to unpack than set up so novices taske note. Cleaning is so easy with no spillage over the floor when you disconnect it from the tank. Overall excellent value for money and highly recommended.
A great filter. Way more efficient and more aesthetically pleasing than ugly internal filters. My only gripe is that the supplied pipes are not really long enough to stand the pump at the tank base etc. (Easily remedied with a couple of pounds worth of longer pipe)
It's great value for money. Good performance but output is not that strong. My nautilus 600 broke so I thought this will be a bit of upgrade but I'm a bit disappointed with the water flow on the output.Using it for a marine aquarium which need a somewaht stronger flow and this almost do nothing except stir-up the surface of the water. So if you want a strong flow from the output then don't buy this as there's not much presure in the output. If pressure flow was same or better than my old nautilus 600 I would have given this an extra star.
Noisy filter. No matter what I do it just wont work properly. I have 18 tanks and this is the worst filter noise and leak wise Ive come across. Incredibly disappointed in this filter! Would not recommend at all! Save your money and buy something else!!!
Adjustable flow rate so perfect for 4 foot and smaller tanks, i replaced my cheap knockoff canister filter that claims to be 2000L/h with this 850L/h. Needless to say it is more than enough for my 4 foot fish tank. Quality little unit. I would recommend.
Has a pretty good build much easier to start than nautilus and aquis. Sadly weaker tho. Expected a bit more power
