WOOHOO!!! Got it fixed. Now everything that I have hooked up is working as it should... only thing is that's 1 out of 3, lol
Hopefully it's just a matter of repeating what got done right on the first

Well, started cleaning things up a bit now that most everything is figured out. But now that I unhooked a couple things, I can't remember how they go back together.
 Here's where I'm at now. I took the HLG drivers out of the box. I was originally going to put it all in the left upper cabinet of the tank stand, but that put it in the same compartment as the overflow. I eventually thought that would give me moisture issues with the electronics so I mounted everything to a piece of plywood which will sit in the roof of the cabinet. I'm still looking to extend the TFT screen and mount it somewhere where I can reach it, but honestly, even if it just sits up top, not visible, it's not that big a deal. It's not very often I'll be changing anything with it regularly anyway. This is what it looks like now:   Now I just need to remember how the heck to hook up the HLG drivers. I've got the LED's in series hooked up to the V- and V+. But the Dim- and Dim+ are the wires that have me stumped. I think the Dim+ goes to the PWM pin on the Arduino... And the Dim- to the ground plane of the Arduino..???? I think I may be losing my brain cells... Anyone???

Cool, thanks! I've run into another potential problem, lol. I guess the HLG drivers need a 10V pwm signal but he Arduino only delivers 5V.
So now I need to see if the drivers will work at all (just at 50%) or how to convert the signal...

So I ended up buying a converter from Coralux. We'll see if that works.
I've got everything hooked up and fired it up today. First time I did that with all 3 fixtures. I have run into a couple problems: 1) The TV string doesn't work at all 2) I have some voltage bleed on one fixture so 2 of the 3 OCW stars are always on dimly 3) The XML NW string comes on but it's not anywhere as bright as it should be - no doubt because of the 5V PWM signal instead of the necessary 10V PWM 4) The XML CW string runs backwards - turn it up, it dims - turn it down, it gets brighter - so it never shuts off - I have no idea  BUT, on the positive side, the cooling fans work flawlessly - something that's been wrong for a while but now seems fixed. Here's a shot before I fired it up - I figured if it blew up and burned to the ground, at least I'd have proof of what I built, lol  And lo and behold, it actually working

I got my converter in from Coralux and I think I have it all figured out how to wire it. But I'm now looking for some of these:
