This is the smaller version of the tunze wavebox meant for 35-200 gallon tanks. I bought this in 2014 and then got a bigger tank and different pumps. I kept this because this thing is a beast and can throw a 2” wave across a 75 gallon tank. I was going to hook up another lagoon tank and use this but I won’t be doing another tank.
YouTube what these things can do in a tank and you’ll be impressed.

*The very first time I cleaned this I dropped and the magnet popped off the back, it has been fixed and used for over a year since so other than that this is like new.
