Eurobracing means different things to different people. With Acrylic tanks, the term refers to extra large port holes. With our tanks, you will get this automatically. Some customers want us to make their tank with larger than recommended ports, just ask Chuck. Sometimes we can, and will, and other time we just can't. The last thing we all want is for you to have problems with your new tank. I like to sleep at night, and feel you do too. But at the end of the day take your tank builders word, and go with it. Don't listen to the person who says he has a 180 with a 3/8" top with 2 ports that are 28x20.
