I just put one together on my 55.... Depending on how big your stand is I would recommend a 20Gallon Sump/ Refugium for your system or larger if you can fit one under your tank. I had to do a 10gallon since I only had room just for that. Check out what I did with mine.
The Over flow box I got is an Eshopps off of RC for real cheap almost brand new if you can find someone that is offering one for you I would get it. 2nd I got a Return Pump, I think Mag Drives are a good brand to get I have the Mag 7 since my Overflow was rated for 800GPH my Mag7 is rated for 700GPH this should do the just fine.
Here is my Sump I drill the hole myself with a 45mm Glass drill bit from BRS
You will have to do some plumbing If you do it you can use 1' PVC
