Just got my light little help?

[as1720]

1x 250W DE HQI,
2x 65W Compact Fluorescent,
4x Dual Bluemoon LED
Which one do i turn on first? And how long do i leave them on?
Should i turn the fan on as soon as i turn the light on?

The LEDs you can leave on 24/7 if you wanted.
Setup a schedule that works for you. If you're only home at night leave the lights off during they day and turn them on later.
Aim for about 8-10 hours of halide, and 10-12 for the PC actinics. You can always add or subtract time if you need to. Have the PC turn on an hour before the halides, then off an hour after.

Here is the plan!
7 am i turn the 2x65 on
9 am i turn the MH on
5 pm i turn the MH off
and leave the 2x65 on till 7pm
Its only a 29 gal tank, do you think it will get too hot? Should i buy a chiller?

You have 500w of halide over a 29?!? Holy cow! Depending on how the fixture is mounted you may need a chiller, or at least a fan across the top of the tank. Keep an eye on the temps for the first day.
I leave the fan for my fixture on 24x7, that way there is no possible way for it to not come on and the fixture get ruined.

The MH is only 250 watts Its a total of 380 watts.
Its about 4 inches above the tank.
The light does come with a fan.

Oh, I somehow thought it was a dual halide setup, lol. Thats much better. Id leave the fan on all the time. The tank will probably get warmer than normal, so you might have to get a clip on or box fan an point at the water surface. If this seems to remedy it, there are company's that sell special tank mounted fans.

I ran it for 5 hours today and it went up a couple dagrees. We will see how it does tomorrow i think i might be lucky and not need another fan!

if need be you can raise the light up higher than that as well. also the fan they were mentioning is separate than the one that comes installed in the light. it would be aimed at the surface of the water to aide in evaporative cooling
