How do you like your Jebao 1200? I am looking to replace my current external pump with something wake because its so noisy. I was looking at the variable speed pumps so I can fine tune my flow, I also really like the "feed" button on there. The aquarium I am looking to use it on is a 180 gallon, so with the sump around 200 gallons total, and would be running about 8 feet of tubing for each over flow. Was thinking about getting two pumps, one for each return line, but wanted to see what your experience with this pump was.
