Okay, so new update:
Dunno if its related but came home tonight and noticed my filter was putting out MUCH less than noraml. Went to investigate thinking it might be the net I have over the intake - My AC likes to eat ghost shrimp or other small fish - and when checking the filter i noticed a little bit of algea (?) on the lip of the water - out spout. I removed my media and saw some of the stuff in the filter. I reached in to knock some loose and knocked a good portion out from near the impeller. I pulled out any large chucks. It was snot-like in texture/consistency and was slightly brownish pink but not like hard core. Dunno what the stuff is...
