Plan B for my 190g

[Veng68]

does anyone remember that crazy wave "box" made by either tunze or ehiem........... They had a video and the aquarium was generating 3-4 cm waves rolling legnth wise.

I think people on RC were commenting on the silicone seal not being able to last for too long if it ran for over a year with such waves.

does anyone remember the name of this device or who makes it?

I thought I had book marked it but I did not

Cheers,
