i didnt order from these people. i ordered from amazon, and thought i was getting a unicel filter, though i may have misread something. read the area in the center of the page in blue. http://www.rjfiltration.com/

everything you said makes sense about the distilled water so i will get some to have on hand. no stains from the xtra blue, and i used plenty of it. so, the green to clean should not cause me problems, or cloudiness? i only used 1 pound and followed the directions by adding shock after.
