Penn Plax Cascade 1500-350GPH Canister Filter

Will this include an installation manual and all the tubings? I am new to canister filters and I want to know as much as possible before purchasing 1

Will filter work for a 100 gallon tank for my red ear slider turtle?

What is the difference between the 1000, 1200, and 1500?

yesterday i cleaned out my filter and i put it back on but it wont suck in water from the pipe there is no pressure even after i pump it. why?
