I bought a used XP2 canister off Craigslist recently, and I'm not sure how it's supposed to work. The interior has media baskets like my Eheim, but there's no standpipe to take the incoming water down to the bottom of the canister. There isn't even a hole in the media baskets to accomodate one (the bottoms of the baskets are full of little holes through which water could pass, but nothing that seems to direct flow). When I put it together it looks like the water will flow fairly directly across the very top of the first basket from inlet to outlet, bypassing nearly all the media I put in there.
How is this supposed to work?
