So, I just got a smokin' deal on a complete good-as-new Cascade 1000 canister filter. Paid $20 for the whole thing. Anyway, I just looked through the box and it didn't come with a manual. I have never worked with a canister filter before, so this is completely new to me. Does anyone know where I can get a copy of the manual for this filter? I tried googling it, but didn't come up with anything I could use. :;dk Thanks!!
