SPS Lighting

[Sniperhank]

Oh, and added a jbj nano glo for the fuge that'll be going up in my sump

You can use any 5000k- 6500k lamp for that purpose.

 

[Sniperhank]

I'm aware, but I have been unable to find one that will fit my fuge section. The jbj is for a nano and fits perfectly.

 

[mr_X]

Sure. I don't have any pics of the bulbs themselves, but I have two FTS.

2x ABS, 1 Blue plus, 1 Purple Plus-

1x ABS, Blue Plus, Purple Plus, Coral Plus-

but what if you used 2 blue plus and 2 coral plus?

but what if you used 2 blue plus and 2 coral plus?

I don't think I'd like it. I don't like a really blue tank. For me, this is the perfect combo. I've seen some tanks that were really blue and they just don't appeal to me.

 

[carey]

I was thinking of adding two of these in place of my aquablue specials. i happen to like a blue tank, but I dont want it like obnoxious blue

 

[Gti_Leo]

to blue looks a little off yeah like when people go 5 blue plus and a actinic or daylight. corals jus don't get the growth with no red or green

 

[mr_X]

That's not true. It's all about PAR. These are all full spectrum lamps.

 

[Gti_Leo]

not really, a blue plus targets a bit of purple and green but not much green and red

here is the purple plus to compare it is more of a full spectrum then the blue

 

[Gti_Leo]

al spectrums are differn't the coral light and the purple plus are more similar besides a slight differnce in green and orange

 

[mr_X]

All you have to do to feed symbiotic zooxanthellae is hit between 300 and 700nm. The rest is just for the naked eye.

Aquarium Lighting; Reef, Planted Light Information. PAR, Bulb, Watt, Kelvin, Nanometers, MH, LED.
[FONT=Verdana, Arial, Helvetica]it is noteworthy that Fluorescent and even more so incandescent lights produce a lot of yellow and green nanometer light, which research indicates is mostly wasted energy in terms of the needs or freshwater plants and SPS Corals. This is where an LED Aquarium Light, Metal Halide, or even (to a lesser degree) T2 Lights excels as there is much less wasted yellow/green light.

still the light output that the ATIs put out are not huge in those areas but they are missing the red spectrum which is a spetrum that does need to be fed to stimulate the growth

PUR is that fraction of PAR that is absorbed by zooxanthellae photopigments thereby stimulating photosynthesis. As noted above, PUR are those wavelengths falling between 400-550nm and 620-740nm.


Generally a Spectrograph is used to rate PUR (these are much more expensive than a PAR meter, with the result of many falsely considering PAR and ignoring the more important PUR.)

It is noteworthy that whereas higher plants (generally kept in planted freshwater aquariums) require more of the infrared aspect of the PAR Spectrum while the zooxanthellae found inside many sensitive corals require more of the Blue spike 400 -550 (465-485 in particular according to more recent research). For this reason either/both higher Kelvin Daylight and actinic/blue is required for many reef aquariums.

I don't see anything in that statement about red.

 

[Gti_Leo]

620-740 is the red spectrum

 

[mr_X]

So, it's not saying that you need the red, it's just saying that you can use the red.

 

[Gti_Leo]

zooxanthellae issstill a plant organism which is still stimulated by red spectrum correct, more blue might be required to stimulate it but i do believe that ts stimulation depends on a full range of light which includes reds.

it has also been said that SPS grow better when there is a red spectum present

 

[mr_X]

Said by who?

 

[Sniperhank]

ANYWAY, I ordered a fiji purple, blue +, blue special, and a coral plus for my T5, a jbj nano led for my future fuge (50 bucks is a great deal when all other lights that weren't led ran 40-45), and a 750 PH to put me over into free shipping land. Really excited now!

i've always read that low kelvin lamps with stimulate zooxanthili growth much better then high kelvin lamps increasign coral growth, but high kelvin lamps suck as the blue plus will pound out alto more UV light and a corals ability to fend of the UV rays like a humans skin is to use it pigment to block it out, which is why we get darker and our color tends to pop, and a reason people that live closer to the equator and in tropic countries tend to be darker then those that live further away and in the ways of corals they tend to bring out more of their natural color and pop more. which is why the addition of a 6500k lamp is used in some of the larger fixtures or the specialty bulbs like the fiji purple and purple plus
