Anyone running a wp-25 in a 40 breeder?

[milou]

I had a WP25 on my 40 breeder and it was a bit too powerful. It blew everything on it's path and turned my loose shrooms upside down and carried them like a whirlwind. It also create a bare patch on the sand. I have another wp25 on my 90 gal 3 ft tank and it's ok. I guess the problem was the 40 breeder is too shallow and putting a wp25 will create a lot of turbulence.
