I was a very busy boy yesterday. I finally got around to hanging the new light fixture, but had to make a few changes first.
I ran a new 15 Amp circuit from the basement. I already had three circuits for the tank but the air conditioner/dehumidifier was on one and didn't leave a whole lot of juice for much of anything else. So now I've got three dedicated circuits for the tank.
With the added flexibility of another circuit I made some other changes: The two MP 40's and two powerheads are now on separate circuits from each other, so if one of the GFCI trips I still have the other two PH's running, as well as the big return pump which is on a third circuit.
I used to run the old lights through the controller but the new light draws too much juice for the controller to handle. The light is on three timers: one for the MH's, one for the T5"S and one for the LED's. The controller runs the two heaters in the sump, the sump light, the ATO system, dosing system and the tank and sump fans.
I was a little concerned that the new lights would overheat the tank and I would have to run the air conditioner more often. Yesterday was a warm day and I watched the tank temperature closely. No problem. The controller kicks the fans on at 81 degrees and they only ran for about an hour at mid-afternoon. Tank temp. only reached 81.2 without the air conditioner being on, so all is well.
As for the new light: Whooooaaa! 1512 watts is a lot of light! (the old fixture was 942 watts) I hung the fixture 16" above the tank and ran the lights on a two-hour on/two-hour off schedule. As the animals acclimate I will lower the light another 2" and work up to a 7 to 8 hour schedule for the MH's and 12 hours for the T5's.
