 Justin,
Probably cyanobacteria.  Have a few questions for you...  
- your test results look a little wonky.  What brand of kits are you using?
- are curing new LR or do you have cured LR in the tank?
- how big is your tank, how often do you do water changes, and how much do you change at a time?
- how often do you clean the media (in outgoing changewater, not tap which will kill your bacteria) in the AC 500's media chamber?
