Thanks to both of you for helping me out.
I have not tried to get rid of it yet because I wasn't sure if it was normal. I've had my tank running for about 2 months now and just don't what is normal cycling and what is not. This apparently is not normal. This Saturday I will try to get it out as suggested during my water change. Afterwards I will see if it returns.
I think my water flow is low and my cleanup crew are few, so I will try to rectify those as well. As you suggested, I will hold off on the chemicals until all else fails. Its good to know what to use though. Very much appreciated.
