Switching from mh to t5 u think be beneficial for sps?

I remounted the lights the long way and it looks way better I pulled the fixtures in closer touching to fill in that spot I was talking about ..... In a pro ati hanger now done it so many times already!!! The only thing that's gonna be a pain is changeling out the bulbs I will have to pull the fixtures down or loosen them to get bulb out due to the canopy if mo reads this how do u swap out lights in your pics looks like u have a canopy as well?
 
Hi Brent.

I can stand next to my tank. The side fixtures I tilt towards me.
The middle fixtures I can slide out behind the the tank....

They aren't in a canopy, the tank / lights/ sump are all in a different room. The front pane is walled off.. You can see it all on my tank thread.

How high should I have the fixtures over the water? My tank is 24" deep .... Right now I have them at about 8.5" from the water line maybe 9?
 
Most have them closer, like 5". I'm like 3".
Closer would be better but not a biggy. Just make sure you get the coverage you need. I guess the closer you have them the hotter your water...
Did you get the dusk/dawn figured out?
 
I get it .... I'm am a total reef geek as well you have no idea the things I do to get nice corals ect....I was going to Garret's acropolis every weekend for months spending 500 a time
I'll have u come check it out soon I owe you for all your help!!
Thank you Brent, I'm a reef geek, what can I say...

I have my 8 bulb 7" from top of tank. This leaves the fixture about 8" from surface of water. Great PAR from sand to top of rock work.
 
Thanks for the replys I moved the fixtures down to about 6" my only prob is I have so much current I don't want the fixtures getting sprayed with salt water .... Otherwise I would have hem 2" off the surface :)
 
I'm running 6 radium 3 400 3 250 on a 500 gallon I've always admired tanks and the way t5 look exp... Ati my question is u guys think it would be a wate of time or not be better? Also my electric bill is crazy I'm curious if the t5 would help that as well ....I basically asking if it would be pointless or a noticeable better change?

i'm switching my 2 400 watt mh+12 bulb t5 to just 12bulb t5 today I'll let you know how it goes
 
I'm loving the t5 change so far ..... Another question is how long do most of you guys run your t5s?? I'm seeing some as long as 10hours and the 2 bulbs 12
 
Another I flipped the fixtures around so the hot air goes out the opposite side not where they touch

No more than 12 hours and min 4. I was talking with LFS that they have done testing of 4 hours on and 4 hours off for max growth.
I have my leds on for 11, 2 t5 for 9 and other 2 t5 for 6.
Are the fixtures setup with 2 switches, each 4 bulbs?
I would do 11 and 6 hours, all opinion...I try to save some $.
 
There's 2 bulbs on each fixture that are controlled seperate with a diff plug I run those 8.5 hours and the all of them for 7.5 I'm noticing some of my ACROS changing colors that I never saw with metal hilides lighter in color or pigment ... I'm happy with that
 
I currently run 10 hours total.

8" from surface of water.
