Well, I got a bigger check than I thought I would (birthday tomorrow -- I know it's sad I rely on birthday money, but i'm 19, haven't had a job in 2-3 months, and have no car...).
I can almost certainly get a decent power filter. The one I have now isn't exactly top-notch (petco brand "Power Filter 65"), but it does extremely well. It has a BIO-falls media that hooks onto the water output too, for extra BB surface area, similar to BIO wheels...
I also just realized my 10% discount is off of my entire purchase.... Sweet.
