Have a 65 gal here too. I did use a 20L for a sump that houses a CS6-1 ER, center refugium and a mag 9.5 for a return with a T feeding a chiller also that returns to the tank. The flow with a 9.5 is fine for me this way and may go with a 12 due to all the T`s. The way you have yours set up a 9.5 with a by pass will work great. I had a Mag 7 on it and with the head loss from it the return flow wasn`t as strong to the tank.
A 20L and Acrylic here in the US ran me about 60.00 total so it was pretty cheap
I can post pics later if you want.
I also custom built a canopy to house 2- 250watt MH with actinic T5`s for supplement for pretty cheap also.
Also your stand with a 36" span should be fine with that stand. If it was a 90 I WOULD brace the center.
