Stepback,
With the pump mounted in the case, do you notice any sort of hum or vibration when it is running (even the slightest bit)? The hum of my Eheim 1048 pump is seriously amplified by my case, so I'm looking for something as close to silent as possible. Plus a 12V hookup to the PSU is nice
Also, what type of reducer would I need to go to 1/2" ID tubing?
