today I bought a Top Fin Powerhead http://www.petsmart.com/product/index.jsp?productId=2752212&lmdn=Product+Type I bought it to defuse my CO2 but, now I'm regretting buying it because its so noisy It sounds like when the impeller is not placed correctly. I have checked the impeller and it seems to be fine has any one else experienced this?
