2 HOB Overflows for 75 gallon?

[tdubrow]

I'm running an Eshopps PF-800 overflow on my 75 gallon fowlr tank. I have another one thats not being used and was wondering if I should put this on the tank as well. Would this be overkill? Should I even bother?

If it was me I would just go with the one for a 75 gallon tank. No reason why you cant though. Just seems unnecessary to me.
