Fishy Passion

I got a powerhead from a LFS yesterday. The guys there introduced me this model they said would be suitable for my 2ft tank..

When I got home and tested it.... gosh... the thing was so strong that my overhead filter nearly overflowed... and there was nearly a mini tsunami in the tank!

So I thought I could bring it back to the shop for an exchange.. and when I was there... the people said that it was already used and initially refused to do an exchange for me... until one of the people said that I would have to forfeit part of the money for the previous pump..

I was like... it was not even my fault.. when you guys were the people that recommended me the pump...

Sigh..
