That's 1152 LED's spread apart 1.8125"

My question is I was told to use Fadecandy with OctoWS2811

Am I suppose to use both firmware or pick between one or the other?

And PaulStoffregen if you read this can you please clear your inbox so I can ask you something privately?

Also should I use ws2811 or ws2812b
I want the brighter of the two.

Fadecandy seems to be a standalone controller for ws2811 leds capable or running 512 pixels per board.
A teensy can run 4000+ leds per board...
Seems like you need to decide which system to use...
i have both ws2812 and ws2812b and can't see a difference in brightness...

You can install the Fadecandy firmware on the Teensy.

Do you know if there's any brightness/color difference between the WS2812/WS2811?
 
In both products the ws2811 chip is embeded in the led housing, ws2812 and ws2812b refer specifically to the smd led form factor.
 
They're all the same WS2811 controller chip, just different packages. My understanding is the "B" of WS2812B means it's in a 4 pin package instead of 6 pins, which allows the strip to have better power and ground layout. For long strips, the poor conductivity of the strip material is quite limiting, so that improved layout really does help. Still, it's not a good idea to have more than about 100 long without applying power from both ends.

Fadecandy isn't a PJRC product. It appears to be mostly based on open source code I've written, but when you buy that product, not a single penny goes to PJRC to support more development (and PJRC is mostly about developing open source software rather than selling as many products as possible, so this is fairly important to keep development going). If you have tech questions about Fadecandy, best to contact the place where you bought it, rather than posting here.

I answer many questions daily, some involving tracking down bugs in code (often 3rd party libraries) or actually connecting 3rd party hardware.

Please, post your question here on the public forum. Only specific questions about PJRC orders belong in private email, and usually those should go to Robin (eg, reply to the confirmation email you got when you placed the order).

If your project is a commercial or proprietary project, you'll need to go to a little more effort to scrub any confidential details, and then you can post here.

Especially if you're using only a non-PJRC product, do NOT send private email to me.
