new tank what to do

[Daframer]

Hey all I just got given a nice 150gal tank with stand and equipment. I currently have a 50 gal cichlid tank and a 50 gal community tank with barbs, tetras and guppies. I am thinking I might make it into a fowlr tank but the wife isn't too excited about about the start up cost. I would really like to try the fowlr. What would be the bare minimum that I would need to get going? Not talking about fish yet just got equip, sand/crushed coral, rocks, etc.

Thanx in advance
