Even though its still new, I hope their quality did not get jeopardized for the smaller more inexpensive pumps. Tunze makes quality equipment. You can always shoot your questions/concerns over to Roger on ReefCentral in the Tunze forum. If you don't get any hits here, he could possibly research it for you. He is located up in Austin and for those that don't know, he is also the Tunze USA representative. Nice and convieneint. ;)
