Finally have a real light but I have a few questions. It has 2 10k halides and 4 blue actinic T5s. Should I swap out 2 T5s for some full spectrum? I dont run my halides all day like the T5s. Im trying to simulate a normal day. Here is the schedule.

T5s 7am to 9pm
Halides 10am to 5pm
LEDs 9pm to 7am

If the halides cover the tank then I think it is your preference. If not I would go with a couple of t5's to supplement.

nothing wrong with that schedule. Give you some time to really see the corals pop in color too! I would, however, not keep moonlights on all night long. There has been research done that shows that fish and corals need complete darkness for a period during the month. I would have the moonlights turn off say from 4am to 7am. I would also set up the timer so that you might have 2-3 days of no moonlights every month.

That is interesting, havent heard that before. I would have to add another timer to accomodate that schedule or would just turning them off all night once a month be adequate?

The whole tank get coverage from the halides when they are on. I was just concerned about when only the T5s are on.

To be honest with you, I think it has more to do with coral spawning. I do know that if the moonlights are too bright, fish will cruise around and not sleep, when they should.

If you can remember to turn them off I'd got at least 2 days a month of total darkness.

The time frame that you have for the halides is adequate for growth. If they cover the tank then you should be good. Having a few full spectrum and actinics vs. just actinics would just be a preference thing IMO.

Having six T5's on for 14 hours a day seems a bit long to me.

Its 4 80W T5s. Too much? Also I have a Ric that has been kinda closed up since I put the pumps and light on. Its only been about a day and a half, should I wait to move it?

It's probably trying to get used to the new lights. If it doesn't get better move it to a less lit area. You can slowly move it back to where you want it.

If you have made big changes from the previous set up I would move all my corals to the bottom and even shade some of the more sensitive. Then slowly start moving them back up. Like Josh said, they might be pissed because they are not used to so much light.

Some gold/brown zoas arent happy but i cant move them any lower, nor the Ric. Was wondering if the Ric doesnt like the added current. If it doesnt open up more today Ill move it to a location with less current.

I have had Ric separate from the rock they were on because they didn't like the flow. Never found them.

T5s 7am to 9pm
Halides 10am to 5pm
LEDs 9pm to 7am

I have about the same setup on my 72G bowfront. For the T5s it has Two actinic lamps, one 22K or blue lamp, and one 10k daylight lamp. The Halides are pheonix 15K lamps. My halides are only on 5 hours a day. My T5s are on 13 hours.

I only put a 10K lamp in there because it was too blue of a viewing light, there really isn't enough light comming out of these lamps to worry about full spectrum lighting, and corals mostly need blue light anyway.

You can also maybe move the light up a few inches. And gradualy extend your halide time until thing are used to the new lights.

Good idea but unfortunately it cannot be hung from the ceiling. I just moved the ric out of the higher flow area. Hopefully it will do better. I think what I will do is for the rest of the week only use 2 T5s, next week add the other 2 T5s then gradually add the halides the week after 2hrs at a time. Make sense?

That sounds good jason. Just watch how your corals respond and you can adjust accordingly.

If your T5's have 2 circuits I would try running 2 blues with the halides and add a ATI or Gisemann Aquablue and KZ Fiji Purple for the other 2 lamps. The Aquablues are bright white with a hint of blue and the Fiji is slightly purple. Running those with 2 blue lamps will give you a 15K kinda look that is nice, assuming your blue lamps are decent.

just as an example

7AM 2 T5 blues on
9AM Aquablue and Fiji Purple T5's on
11AM Aquablue and Fiji Purple T5's off, Halides on
6PM Halides of, Aquablue and Fiji Purple on
8PM Aquablue and Fiji Purple off
10PM Blue T5's off

You could even add the Fiji Purple and Aquablue back in for a couple hours during the halide cycle. If you have decent reflectors they will add a bump to the PAR that would give a high noon kind of bump to the intensity.

I have 4 T5 80W and 2 halides 250W

WOW! you guys run 15 hrs a day of light? And this sure does seem to be a whole lot of light. This is on a 55 gal correct?

I wouldn't, was just chiming in based on his timing. I personally would never go more than 13 hours.

Sunlight at the equator is about 12 hours a day. Very fast sunrises and sunsets!

I run my lights about 11.5 hrs a day with only about 8 hrs of halides with my PC lights providing my sunrise/sunset light.

15 hrs of light on this tank is excessive, but the fact that there are 2x250w halides, AND 4x80w t5s really seems like a waste for a tank 13 inches deep. My 150w provide over 250 par at the substrate...

There is a great discussion over on RC about photoinhibition and the effects on corals. There are a lot of hobbyists that only run their MH 4-5 hours a day. I know there was a marine biologist that was running 6500K MH for maybe 2-3 hours a day and had incredible growth but no color. This was a few years ago.

Its a 120 Gal 24 inches deep. So is that too long of a light schedule?

Corals need sleep too. You really should keep the light period down to close to what they would have in nature. Many corals feed in the dark so leaving the light on longer can actually hurt growth in the long run.

I cut my time to 12 hrs, 9am to 9pm. So do most of you have a period of complete darkness everynight?

Don't cut it all at once, reduce it down by 15 mins every week or so till you are at 12.

My lights go out at 730 PM and my sump lights go out at 1030 PM. That makes the room dark till the sun comes up. My lights come on at 1230 PM.

Ah... makes much more sense now. As murf said, decrease it slowly. My tank sees about 5 hours a night of complete darkness. I am sure most people here do..
