The T5 Q&a Thread - split

^^

I think (for lack of a better word) we could dumb this down a bit. Prob. 80% of the people asking bulb questions in this thread don't care about the nitty gritty. They want to know which bulbs look pretty blue and can grow SPS using X fixture. KISS method works here.
 
I know I wanted to have bulb combos/fixtures with pics so people can see what the different combos will look like before they spend the money on bulbs they may not like.
But then the issues of camera white balance and how difficult it is to represent what the eye is seeing with a camera, not everyone is a photographer, not to mention every computer screen is a little different color so it would look different between my iPhone, iPad & Mac & PC.
 
hey guys not to break good conversation on something that would be totally awesome like one of those charts even if there is a diff in color for every screen you have..... but i have a question that i cant find to answer myself. i have been looking for diff combos for a 4x80w` setup but cant find anything that just has great growth and ok coloring.

also after that is answered i have to tell you that i had made an impulse buy and lets just say it was a 150 dollar mistake on a 72" odyssea fixture do you know if there is a retro fit upgrade that i could use on that fixture. if not a whole retro fit setup maybe just the reflectors that may fit on it.

Thanks in advance and next time i will be doing more research before buying.

right now i have this setup but have to change anything is better than what i have

front

10000 daylight
actinic blue
10000 day
actinic blue

back

they are all the bulbs that came with the fixture itself odyssea brand

Great growth/decent color
1 GE6500 / aquablue special for more blue
2 blue plus
1 purple plus

Your better off buying a new fixture.
 
Blue

2. Fiji Purple or ATI Purple Plus

3. Aquablue

4. Blue

So this will give me a blur looking tank but will it make my corals grow better
 
i looked at that but it didnt tell me which spectrum gives me the best growth but i think i have figured it out threw searching for the last 2 days......... the lower the kelvin rating the more growth you will get but the crapier the colors you will be able to keep. as you move up in kelvin the better colors you can keep but you will get less growth the further up the chart you move.... the only thing i dont understand is how the nm relates to all this.
 
Low kelvin like 6500k & 10,000k is more yellow & white looking, it is very intense light that grows coral vey well. Higher kelvin like 15,000k-20,000k equals more blue looking color & has better coral color but usually less intense light, especially with halides but blue T5 bulbs are very strong so this doesn't apply as much with T5.

Think of it like this (in a easy to understand roundabout not very exact kinda way)
UV light- 420nm actinic (violet)- 460nm blue- 3000k red -6000k yellow- 10,000k white,15,000k white/blue- 20,000k+ blue
 
You like this? More or less blue than this?
2 blue
1 purple
1 ge6500

A lot of us consider this not blue enough.
 
Simply double checking before I order... Looking for just a tad more blue than a 14k Phoenix with all colors well balanced and bolstered.

36x36x27 SPS Tank. 10x39 Powermodule.

5x ATI Blue Plus
2x ATI Coral Plus
1x GE 6500
1x ATI Actinic
1x ATI Purple Plus

that is a nice combo- covers every spectrum.
Not sure how close to Phoenix it will be though. Pretty close.

Never had a 10 bulb combo to play with though....
Here's my 150w Phoenix 14k over a couple different tanks.

I always hated the Aquablue Special, maybe I'll dump the Actinic for an additional Blue Plus

What about the KZ Koral light 10k.
The ge6500 may work well in that combo, its a cheap bulb that is a growth monster so it could work nicely placed right near the middle of the fixture.
 
One of the reasons I was concerned about the ge6500 is unless your fixture is raised a good amount above your tank you may get a bright yellow band of light that is noticeable, a 10k bulb may not have a effect as bad as the 6500k.


One thing about the Phoenix I noticed (@ least with my setup) is it has a purpley hue to it. Even a green-ish hue sometimes, (6500 may be great for this) but its more noticeable in my 29g. Maybe its the glass?, not sure...

Ive never liked the GE 6500k...just too greeny/yellow for me. It is difficult to compensate for the yellow...with 10 bulbs you could prolly do it but have you thought about trying the KZ coral light bulb 10000k bulb or the KZ New Gen 14000k bulb?

If youre truely interested in achieving that yellow peak...the UVL aquasun is a nice bulb. Gives you the yellow but has more blue in it to not appear so yellow (actually looks pinkish). Not as much par as the GE 6500k but still a solid bulb thats not too yellow. Even the UVl 75/25 (not the biggest fan) has a little yellow in it although its more whitish bulb.
