Question on penn Plax 1000 canister
So I am building a new 65g aquarium. I bought my first canister filter. Penn Plax Cascade 1000.
The manual clearly states the filtration works from bottom to top.
But it says the order of the media is carbon in bottom basket and course/fine aponges in the top. Floss in the middle basket.
My confusion is I am seeing, which makes sense, is the the order from bottom to top should be mechanical filter first, then bio, then chemical since the water flows from bottom to top.
I'm not is a position yet to plug it in and see which way the water flows.
Anyone use this filter that can steer me right?
