I use Savko. but its not local. I gave up on finding local. I have a few buckets with black pieces I will look for 1 1/4" tomorrow. I can sell it to you for what i buy it for. I also have the black PVC pipe as well. If you need it.
Matt, if you want to paint a regular piece of pvc black, but are worried about getting the toxins in your tank, I have some paint for the bottom of a boat. Its non toxic and looks good. Used it for something in my tank and worked great. If you want some I have some if you want to stop by and grab it.
