Review on 🐠 Superior Flow Control with Tunze 6020.000 Nano Stream: Unleash the Power in your Aquarium! by Lynn Cook

Unless you have something that requires a very high flow, this 6020 is way too powerful for a 10 gallon tank. My cleaner shrimp hid from the current. It's so powerful. According to the instructions it is the same as the 6040 and the only difference is that you can use a controller that controls the 6040 and can generate waves, pulses etc, but it looks like you are NOT connecting the 6020 to the controller be able. It is an autonomous circulator at a fixed level. But it's a very well designed device with durable plastic and metal/stainless steel components. It consists of three parts. You get a very strong back magnet (very), a magnetic end connector that connects to the pump and the pump itself via four soft plastic pins. The connector has a suction-type magnet that works as both a suction cup and a magnet, so you'd better position the circulation pump correctly first, and then install the magnet at the back of the tank to seal it. Getting off isn't easy, which can be a good thing with the right attitude. There is a cheap plastic director that allows you to turn the flow in circles - only in one plane it is configured. So you can rotate it up, down, forward, backward, but not horizontally. You can also remove the guide that allows the water to flow straight ahead with a wide spread. It is very efficient and much more powerful than Hydor 240GPH and even over 425GPH and 600GPH. It's strong - it's talking 660 GPH and I'm inclined to think it can generate a current close to that, although that's a bit optimistic. what you can expect from a quality device. Although this is too big for my fish and blows them away this is a fantastic piece of equipment that I will use if I have a large tank.
