Planned Water Flow for 112G

I'm in the process of planning (and slowly setting up) a 112G low tech jungle tank and I was looking for input on the amount of flow I will have.

The tank is 5 feet long, 18" front to back, and 24" tall. It has an overflow on the left side (about 9" from the left edge). It has returns on the right side with four loc-line flat nozzle jets. Based on calculations I will be running about 400 gallons per hour through the overflow and returns.

In addition I'm planning on placing a Koralia 240 powerhead on the left glass pointing across the tank.

Will this be enough flow? Should I plan for a second powerhead on the right side (where the sump returns are)? Or should I use a larger powerhead on the right side? Any other input or suggestions?

Based on my 30 seconds of research the Koralia 240 seems suited for nano tanks. Not sure if that is true but that does not sound like a big enough powerhead for a five footer. I think going a little oversize makes sense because these things tend to get clogged and over time the flow decreases.

On the other hand, if you already have it then go ahead and try it. Depending on décor density and so on flow may not be a big issue.
