Also check the direction of the fans. I believe 1 should be blowing into the tank and the other bowing out. You might want to flip them around in difference combos to see if that helps

Don't know much about the NC28 but for the BC8, try popping the back part open and leave it open. You could even add a fan there to blow extra air over water but it will increase your evap so ATO necessary.
The fans in the hood are too cool the PC bulbs, not the tank. They are noisy and if you are going to replace them, just buy the same size ones from a local computer store. Spend a buck more and get a controllable fan with actual bearings. I would check the pumps, might just be worth swapping it out. MJ400 or 600 should probably be enough flow (I'm only running a MJ900 on my BC29) and they are relatively inexpensive. Just my 0 cents (2 cents round down now that we don't have pennies... lol)

Thanks everyone. Today I got home and it was 80 in the bc8. Yesterday I swapped the stock pump out for a mj900. Seemed to do the trick.(thanks Matt) Yesterday I cleaned the fans on the nc28, but the lights werent turned on today until I got home from work. So I will be monitoring these tanks closely. If all else fails I will either find an led kit for the hoods or just take the hoods off and get aftermarket lights for them.

Had the same problem with my bc14. after a year I gave up even after switching over to LED's. couldn't get the temp under 82. switched to an innovative 16 and I had to add a heater because it wouldn't go past 71.
The closed canopy is a huge issue, really creates a little oven. Unless your willing to add a chiller, I would look into something like a AI nano or something on those lines to get rid of the canopy.

I bought my NC28 HQI brand new and it was sold as a package with the chiller. I added a HOB skimmer and the chiller has to run throughout the night to cool off the heat added by the skimmer pump. With minimal equipment, LED lights, and a clip on fan blowing on the sump area, you might be able to keep the temps down. I would doubt you could do it with the HQI though without a chiller.
