Howdy folks.
A slimy something has appeared on the surface of Zucchini's water. First time it showed up I did a partial change of water, and it did not appear for about 10 days. It looks oily and is slimy to the touch. Above the waterline is not visible from under the water.

It also did not show up prior to having my XP3... I have the media that came with, and a package of Fluval Biomax bacteria helper thingamajiggers (added later). Anyone have a clue what it could be?
