Me too....I just had to lower the water level a bit. Took out the sponges and am only running carbon and some other packet I can't remember the name of. As long as the water level doesn't go higher than the bottom of the cup. I ran it Sun-Wed and emptied it last night. Some fluid, little greenish, nothing bad really. I would love it if I felt more secure about the Sapphire which is made for us hood-bound folk, but had a bad 1st experience with one in Feb and a worse experience returning it....so I'm a bit gun shy.
