Cannister filters

[Salmon King]

I thought I was luckey.I have been in this hobby for12 years,So many of my friends have emptied there tanks on the floor because of these filters including myself.I thought when they changed from the round to the square type that they were on the right track.All I can say is look out.

It was a few years back, and I hope they have improved, but I would never see a Fluval or a Rena as an option ever again. And it was a Fluval that knocked my husband back across the room...but I think the Rena ended up pouring out more water...
