I'm just finishing my new vivarium and the powerhead as well as the minijet pump that I'm trying to use for a water feature makes enough noise inside the tank that I'm worried it may affect the frogs. The hum ins't really noticeable outside the tank but if you listen inside, ther is distinct low level hum. I've tryed wrapping the pump in some filter foam but the noise is about the same. Any suggestions?
