The T5 Q&a Thread - split

So do we change out bulbs after a year because the PAR drops off? I guess the real question is if the PAR drops is that the reason to change out bulbs? Or does something else happen with T5's that would make changing them out happen?
 
Probably tired of answering this, but it seems you're still actively helping people out here so i'll take a shot:

Getting a giesemann infiniti 1 x 250W MH + 4x 24W T5 fixture. Thinking of the Phoenix 14K MH and not sure on the four T5s.

Suggestions?

Was considering maybe:

1 ATI Blue Plus
1 454 UVL Actinic
1 KZ Fiji Purple
1 Giesmann AquaPink

(but you guys might throw up on that. please let me know)

by the way its all SPS and an anemone. opinions please! thnx
 
I'd do 4 Blue Plus 1 Purple Plus and a ATI Aquablue. The Blue Pluses have all the actinic you need, You could use one in a dusk/dawn position, that's their best use cause once all the lights are on you really can't tell there's one in there.

Hi Gim,
Thanks a lot for the help.

My ATI PM has the bulbs 2 and 5 connected for dusk/dawn.
So, maybe the correct position for the bulbs would be:

FRONT
ATI Blue Plus
ATI Blue Plus (dusk/down)
ATI Purple Plus
ATI Aquablue Special
ATI Blue Plus (dusk/down)
ATI Blue Plus

Right?

And if I would like to try to add another Aquablue Special I could:

FRONT
ATI Aquablue Special
ATI Blue Plus (dusk/down)
ATI Purple Plus
ATI Aqua Blue Special
ATI Blue Plus (dusk/down)
ATI Blue Plus

Correct?

Yeap, I think the higher PAR will be very welcome by the zoas I've got!!

Thanks again!!!
Grandis.

3 ATI Blue Plus and 1 ATI Purple Plus.

It will bring out some colors that all the blue will miss by using one purple bulb. Your mix is terribly pink and will look like...well it will look bad.

Do the first mix. The second mix will be a lot whiter than you think.
 
So do we change out bulbs after a year because the PAR drops off? I guess the real question is if the PAR drops is that the reason to change out bulbs? Or does something else happen with T5's that would make changing them out happen?

PAR drops off and the spectra of the bulbs will shift.

Non cooled T5s need to be replaced every 6 months.

Semi-cooled T5s can make it to about 9 months.

Properly cooled T5's like those in an ATI fixture, can go 12 months.
 
I have an aquactinics fixture with 5 bulbs. Currently, I have 3x blue+ (1st,3rd, and 5th bulb) and a purple+ (2nd) and aquablue (4th position). I'm not a fan of the aquablue or the GE 6500 in this application (have tried both). I'm going for a 20,000K look. Would the addition of a blue+ bulb work here, or should I go with something else? Tank is a mixed LPS/Zoa tank (90 gallon, 2foot depth).

Another blue plus or the kz new generation will work.

PAR drops and spectrum shifts.

Hello Ryan!
I wanted Grim to tell me more about the bulb placement on those schedules than about how much white the second will be.
Well, maybe he would say the same...
But I really appreciate your help! Thanks!

Ok so I am curious about how others run their 4 bulb setups with 2 plugs one for each pair of lights.

If I have 1 ATI blue + and 1 ATI purple + in the front 2 spots and 1 ATI blue + and one KZ new gen in the last 2 spots, should I run all 4 all day or the front 2 part of the day or the back 2..?? see where I am going with this? What combo would be best? Tank will be mixed reef...

Thanks!

Run one set 10 to 12 hours or so as your dusk/dawn pair and the others 5 to 9 hours a day. Just pick a mix you for the dusk/dawn. Either 2 blue plus or a blue plus and the purple plus.
 
Will have tomorrow my first t5 fixture - ATI PM 8x24w - to be on my 29x29x24"
sps cube...

will be running with the following bulbs :

Front to back:
1- ATI Blue Plus
2- ATI Aquablue Special
3- KZ Fiji Purple (plug 2 )
4- KZ Coral Light 10K
5- ATI Blue Plus
6- ATI Blue Plus (plug 2)
7- ATI Aquablue Special
8 - ATI Blue Plus

it seems most do there dawn/dusk like this :

2 bulbs on then all 8 bulbs on...
just wondering, why not do 2 bulbs on then 6 bulbs on then all 8 on ?
thanks !

Not sure I understand the question completely. Why not go from 2 to 6 to 8? The fixture has 2 power cords. One runs 2 bulbs and the other runs the other 6 bulbs.

So you can run 2 and then all 8 or you run 2 bulbs, turn them off, turn on the 6 bulbs and then have the 2 come on again later.
