So my Klir di7 came with one large roll of fleece, but when I buy replacements they come in two rolls of 25 meters each. Does anyone know where you can get a single (or double) roll with 50 meters on each roll (like what came with the unit)? I have two DI7's on a 300 gallon tank, and I end up changing the rolls way too often, and they are a real pain to get to.
