Tunze Nano Stream 6020 Compact and Discrete Propeller Pump for Aquariums Up to 65-Gallon

Tenia muchas espectativa de esta bomba debido a su marca pero me eh decepcionado un poco es potente y mueve muy bien el agua de mi 13.5 galones, pero sucedió lo Q la mayoría de los compradores mencionan es ruidosa, aun tengo la esperanza de encontrar la forma de que no haga ruido

This is a great pump. The wide flow really moves the water in a small tank. I have 25 to 40 gallon tanks. I was surprised to read some reviews indicating it quit working shortly after purchase because I've found Tunze to be pretty dependable. The first time I cleaned it after using it for a few days, mine did not start up again. I took the magnet off the outside of the glass, started the pump and then reattached the outside magnet. Perhaps the strength of the magnet can keep the pump from starting up initially? Don't know, but it worked for me.

I am using this for my JBJ 20 Gallon Nano Rimless AIO Aquarium. It's small compact size and powerful flow is great for my saltwater aquarium. The 660 gph flow rate is excellent, really moves the water around. The magnet holds well, not sure about the silicone isolation pegs they need to be pushed in tightly so they stay in place, but they stop any vibration on the glass. So far the pump is silent, no noise unless you put your ear near the glass. The cord is a pain as it is on the bottom of the pump, it's soft so you can manipulate it into the position you want. The flow director is hard to position under the water, so you need to do it before you place it into the tank. Tunze is made in GERMANY not CHINA. And it has a two year warranty. So far, so good.

The powerhead itself is great, small form factor, good magnet mount, powerful and easily adjustable direction shield. My big problem with this is that those little blue rubber plugs that join the powerhead to the magnet will fall out anytime you want the move the powerhead or remove it for cleaning. Luckily they float, but I have no idea why it's designed that way (noise dampening?)

Tried on a 20 gallons península and looks horrible, is loud and is way too strong for a nano tank.
