New tank with equipment help

[GrandKai]

Hi, I was able to trade an unused musical instrument for a 150gal saltwater fish tank. I had a 55gal saltwater over 20 years ago with a nonstandard setup. Since I was in college I did not have the money to invest in all the proper filters/lighting. In this new acquisition there are many things I am unfamiliar with and some I am. What I need help with is identifying the parts I do have, what I need and how I should properly hook it up. I am visually disabled so I am limited on funds. I will attach pictures of what I have. Not in the pictures is the tank which has 2 overflow corners and several tubs of coral and about 100lbs of crushed coral/sand mix.

Any and all help would be appreciated, have a truly wonderful and beautiful day.

600-2 looks like Maxijets with flow mods. The pump looks like its for the sump.

Thanks for the reply. So what you are saying is that I would hook up the pump in 600-2 to the sump in 600-3? And what looked like to me a power head is a Maxijet with flow mod? Would I hook that up like a power head would hook up on a fresh water tank without the under gravel filter?

I guess I should have put in the original post what I believe the parts are and if I am wrong if you could correct me.

Picture 600-1 (top): RO with cables. I do not know anything really about RO's so any help would be appreciated
(middle): Various heaters of which I do not know if I need all those or not. Testing kit, chemicles, over the back filter and timer
(bottom): Various air pumps of which I do not know if I need that much or more
Picture 600-2 The black boxes are wired to the silver/white cylinder. This looks like light sockets and was told by the person who gave it to me they were grow lights. I could not find wattage on them and do have 2 bulbs that go in them and there is no wattage on those either. The power head or Maxijet and a pump
Picture 600-3 This I believe is the sump and below it is a sheet of glass of which I also believe goes at the top of the tank for support. Can you tell me if that is correct and if so if it is necessary as I would have to strip the silicone off and re-silicone it in place
Picture 600-4 This is quite dirty and am in the process of cleaning up. It has several foam filter type squares on the left side and a thick paper like lining on the right bottom

As a note I have joined a few forums and posted the same pictures and this is the only one to receive any response. I do appreciate all the help.
