New Tank Arrived. Need Some Plumbing Advice...

[hummer]

I'm trying to do my plumbing (first time) by dry fitting all the parts but I've run into a little snag. The Flex Hose I bought from Western Pump are a little too stiff. The distance from the overflow to the sump isn't very far so the flex hose isn't bending the way I want it to. I have a few questions...
1. Do you know where I can get 'more flexible' hose in Calgary?
2. I might decide to go with PVC pipes instead of flex hose. For those who have done that, how do you design it so that it can be dismantled later if you ever need to move your tank and/or sump?

I've attached some pictures of what my setup looks like. Any help you can provide would be great! Pictures are good too. Thanks.
