Thanks all!!
The purple stuff is Purple Grape Calerperla (sp). It kind of works like macro algae would in a refuguim. I dont have any hair algae in the tank since I put that stuff in there.
For the power head, it is just the main return, I have not added one to the tank. I read a good idea though. I am going to use the one that came with that POS fission skimmer. So atleast I can get some use out of the skimmer.
I will get some better pictures tonight when there is no glare coming from the living room window.
