The T5 Q&a Thread - split

Im not sure which two are on a seperate switch but here is a basic layout.

front
1 Blue Plus
2 Purple Plus
3 Blue Plus
4 GE 6,500K
5 Blue Plus
6 Purple Plus
7 Blue Plus
8 Blue Plus
Rear

Your coral placement may change this a little as well as which bulbs are on the circuit of two bulbs. For the circuit of 2 bulbs you may want either two blue plus bulbs or 1 Blue Plus and 1 Purple Plus.

Switch # 6 & 7 around if you want 2 blue bulbs for dawn dusk.

Hi, I am looking for some suggestions for my ati dimmable sunpower 6x24w

Tank is 24x18x 15 high so pretty shallow

Currently I have 4xnarva blue, 1x kz pink and 1xaquamedic 15000k reef white

Bulbs are now 12 months old so seriously in need of changing

I am getting reasonable growth with my spa although colour is a little lacking

I am thinking that I have to many blue plus which is not helping colour or growth , although I like the look

By the way this photo was taken in the evening just on blues

Also I have the lamp about 8 inches above the water level, my acropora prostrata is 3 inches below the water level , it has good growth but is lacking color and looks pale, could this be the lamps to close to the water

Cheers

Mike

It could be flow,phosphate,& numerous things but 12 month old bulbs aren't helping either:thumbsup:.

I don't see anything wrong with your combo myself but if you want to try something else go for it.
I think new bulbs will help, but it could be a combo of things.

You can try a ge6500 bulb or something like that. I would try it for awhile, I like this better than removing a blue bulb for 2 15k bulbs or something similar.

Yes this is off topic. But I'll answer anyway.

1. LEDs realy require a current supply rather than a vlotage supply with a voltage supply if one shortens out the rest will blow up.

2. As far as optics go I do not use them if there is 24" or less between the substrate and the LED's. But I would for anything taller than 24". By 24" though I mean from the LED to the Substrate. So even on a 16" tall tank with no substrate and the LED's 12" above the tank then I would use optics.

In terms of the power supply I was going to run all of the bulbs in parallel to drop the current to acceptable levels and have a potentiometer in series to control the voltage. But unfortunately I'll probably be sticking with the T5's for a while due to a severe lack of funding. :sad2: But thank you for the response. Now I'll let this drop back to a T5 topic and go order some actnic bulbs.
 
I'm thinking I may just need to get over the notion that I need to have a GE6500 in my lineup...

I'm running 6x Blue Plus, 2x Coral Plus, 1x Purple Plus, 1x GE. It's a tad whiter than I want... Should I ditch the GE for a true Actinic or swap the Coral Plus' for more Blue Plus?

36x36x27 150 Gallon, plexiglass shield of the fixture is 8" above the water level... 10x39 Powermodule
 
Thinking about grabbing a 24" 6 bulb ATI Powermodule from someone here on RC. Im currently using a kessil a350w at 100%. I really like the color but want to switch for better growth out of my SPS. The tank is 24x24x14.

I would like a nice crisp blue color compared to Radiums. Is this a good mix? Would you recomend something else?

blue+ (4)
coral+
purple +

Could you also help me with the order with these or what you would recommend?

Thanks!

Well po4 is 0.003, no3 is 4, all other params are spot on...

I think your combo would a little strong in the red. With what you indicated I would bo with

Front
1 Blue Plus
2 Coral Plus
3 Blue Pluis
4 Coral Plus
5 Blue Plus
6 Blue Plus
Rear

Not knowing the order of the 2 bulb circuit I would put 2 Blue plus bulbs in the dawn to dusk circuit. And move the coral plus bulbs to midday. This would give you just a little less red than what you origanaly listed and make the tank slightly brigher with a little more green light.

If you want it just a tab bluer then I would swap the GE for an ATI AQua Blue Special. Or you could pull one of the Coral Plus bulbs for another Blue Plus bulb.

Hi I have an ati 4' 8 bulb t5 fixture.

My bulbs are

4ati blue +
2 purple +
2 aquablue special

I'm looking to get more pop out of my blues and oranges. Colors seem washed out a tad.

Should I add a single pure actinic bulb? What bulbs should I replace?

Added a pic of my tank with all the lights on.

Also, Im going from a Kessil at 100% on a tank that is 24x24x14. How should I acclimate my coral? How high from the surface of the water? Duration?

Here's a pic for reference. The t5 is above the kessil because I haven't gotten bulbs yet. Almost everything in there is SPS btw.

To pop your blues more you may want to pull one of your Aqua Blue Specials for either an Atinic or another Blue Plus. But to get your oranges to pop is another thing completly.

If these are reflective reds then I would think the two purple plus bulbs would be more than enough to make them pop. But if your talking florescent reds then the blue plus bulbs should already have them popping for you and adding either more blue or more atinic would slighly increase that florescense.
 
ATI 6x54 and have the current lineup F-B: 2Blue+, Fiji Purplle, Coral+, 2Blue+. Bulbs are 10 months old and I have the following replacement bulbs on hand to play with: 4Blue+, Coral+, KZ New Gen, KZ Coral Light, and KZ Fiji Purple. The tank looks a little brownish with all lights on. Dusk/Dawn are 2&5. What would be a good lineup w/o the Purple bulb in the mix?

The brownish effect is created by a combination of green and red. Therefore I'm not using the using the New Generation or the ZK Coral light. I'm also pushing the Fiji Purple to the rear where it not make the whole tank too strong in the red spectrum. The Coral Plus already has a strong red component.

If the combo is too purple for you you can substitute the other extra bulbs you have into position 6 to see hape it changes your total effect.
 
New Fixture

New Fixture

I still prefer T5 lighting and got a great deal on a Giesemann Neptune XL 8x 54w fixture. It will come with ATI bulbs which I'm not too familiar with (I've been running mainly KZ bulbs), so I need some help.

Lighting is for a 120g Mainly SPS with some LPS up front. Upgrading to an 8 bulb from a 6 bulb as I wasn't getting the coverage I wanted with the 6 bulb.

Here is what I was running on the 6 bulb:

Front:
KZ Superblue
KZ New Gen 2 (12K?)
KZ Purple
KZ Superblue
KZ New Gen (10K?)
KZ Superblue

I have great color and great growth with that. One thing I was missing was that florescence from an actinic bulb. So this is what I came up with on the new fixture:

Front:
ATI Blue+
ATI Actinic
ATI Coral+
ATI Purple+
ATI Blue+
KZ New Gen (10k)
ATI Actinic
ATI Blue+

What do you think? I've looked at a couple pages of posts, but very rarely see anyone with actinic bulbs in their rotation. Is there a reason? Should I go with more blue+ instead of the actinics? Will the Actinics be too 'white' for my set up?

Thanks in advance.

Depending how sensative your eye is in the blue spectrum you may notice a difference in your lighting between the super blues and blue plus bulbs. I notice it as the blue plus peak at a slightly longer wave lenght closer to a blue cyan compared to the super blue in the truer blue range.

Atinics are on the other side of the blue spectrum where they peak at even a shorter wavelenght than the super blues. However if measure then with a PAR meter you get a lower par reading on them.

Comparing the two spectrums you listed above the first your old one will whiter and the new set up should be more blue. On my personal choice though I would move the 10K bulb more to the front. But I'nt sure which tubes are your dawn to dusk.

I wouldn't bother with actinic bulbs for a SPS tank, stick with blue plus & KZ super blue. The t5o actinics are weak, add more pink than blue, but they are nice for a dawn dusk look. Not great for SPS tanks. I'm running one in my avatar but its only because reefgeek sent me the wrong bulbs, they have a place, but a blue bulb does is stronger and is more blue.(duh)
I believe the KZ new gen is a 15k bulb with a bit less red than the coral plus.
The KZ KORAL light is the 10k bulb.
