In my next tank I'm going to try out the Penn Plax Cascade canister filter, since they have bottom-mounted impellers I won't be needing a reactor. But I would need elbow airline fittings? Would I also need Tee-valves? And I remember Steve Hampton telling me that I should place the elbow at the point where I would want the waterline to stay at incase of a back siphon(during power outage)...would a check valve solve that problem?
