 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. |
