Heres my video. Its with t5 thou
Looks very nice!!!
I would suggest to add holes on the back board of the canopy, by the fans, so the air can circulate for the gas exchange. You can cut some egg crate to fit those holes if you worry about fishes jumping out.
Congratulations on your new reef, man!!!! Looks great!
Thanks for sharing the video!

Any pics with the lights on? Still trying to figure out if I'm going 10k or 14k? I really want to go with 14k to start, but really tempted by 10k.

I posted 14k on the first page. This is 10k.

I already did. Double lol its at 1 min mark. Do i need more thou?

I have two fans blowing in fron the back. Then i have another fan blowing in from the top right side to cool the t5 ballast and a fan blowing out on the middle top.

Well see if i need more and add more in the future.

So I run 2 t5 retrofits and 2 250w halides in an 18" high canopy over a 90. I have 2 fans, one mounted in the top extracting air out at each back corner.

I keep the front cracked open an eight inch and the temperature doesn't get above 80 with the house set at 75. You can feel the draft being pulled in from the bottom front that keeps a cushion of cool air between the lights and water. I almost added two more fans until I figured out cracking the front that little bit made such a big difference.

Old school everyone put fans pushing in because the thoughts were the salt moisture would trash the fan. 4 months in and I only see dust build up. They are so high only hot air gets to them, not salt or water.

You need the vents. The air that comes in (fan) needs to go out (vent) easily for better flow. Not only for the heat, but for gas exchange/air flow for the system itself.
Sorry about the drawing... I hope you can understand.
I know... I'm old school and draw on paper. LOL!
Here is your back board where the fans are and my suggestion of the holes with egg crate:

You could also leave the whole on the top of the canopy (not on the back where the 2 fans are) without that top fan, and cut some egg crate to fit that hole. The 2 fans in the back are enough.
Hope that helps.

As mentioned, it's more efficient to draw hot air away, than to bring fresh air in. Fresh air will always be drawn in when you're exhausting the hot air away.

You can remove the fan on the top so hot air goes up. The air needs to have a direction to flow. This is the way I do:

My canopy only covered the left side and the front of the system above.
The other system I have the canopy covers only the sides and the front.
If I had to have the top covered besides the sides and the front, like my planted tank had for years, the whole back was exposed with a small fan with the clip.
The canopy was on top of this:

Hope that helps.

Yes, correct.
The hot air goes up, so you don't need the top fan, just leave it open.

I'll stick with my set up as it works without such a large fan. Hot air does rise but heat extraction with fans is more efficient. My canopy is enclosed on all sides so there isn't light bleed into the room.
 

Have you ever had a reef tank with no sump and how did it go?
