You have your comparisons backwards for your heater.
you have
Heater
If Temp > 76.5 Then HET ON
If Temp < 77.0 Then HET OFF

I believe you'd actually want
Heater
If Temp < 76.5 Then HET ON
If Temp > 77.0 Then HET OFF

And you might want to put in Temp comparisons to turn off your MH's in case your chiller fails. Like
If Temp > 81 Then MH3 OFF
If Temp > 81.5 Then MH2 OFF
If Temp > 82 Then MH1 OFF

And also

If Temp > 79 Then CF1 ON
If Temp > 79 Then CF2 ON
If Temp > 79 Then CF3 ON

Good eye... :)

were do you sugest i add them?
I can do the these after each light statement.
If Temp > 81 Then MH3 OFF
If Temp > 81.5 Then MH2 OFF
If Temp > 82 Then MH1 OFF

But far as fan cooling. I did not wan them to stay on all the time..
There above each pendent.. I figured have them come on with lights and stay on for 10 minutes more, but if tank was running cold to shut them down. Any thoughts...

My thoughts were to have the fans kick on before the chiller had to run to save on electricity. I can understand not wanting the noise from them though. I wouldn't even have them come on with the MH for 10 minutes since it takes about that long for the MH to even start producing a decent amount of heat.
