So just to be clear about the cost savings (speaking only of the colored pipe, and only what pricing I can personally get):
The colored PVC pipe from BRS for a 1" diameter is $12.99 for a 46" length, and assuming free shipping that's $0.282 per inch.
From Home Depot, a 1" pipe that measures 60" long is just $7.74, or just $0.129 per inch. A big savings for sure. Unless someone has had some horrible experience with this material, I am going to plan on using it on my next build.
I'll also add that I really like BRS from way back when all they did was literally "Bulk Reef Supply" on eBay, meaning, they were a great source of carbon and GFO, etc. Coming back into the hobby I am amazed to see how far BRS has come, and while I try not to be a "fan boy" I think I am

Their videos are really well done and informative, and for that reason alone I'd like to give them my business for the PVC pipe, but this is one of those things that I just don't think I can justify paying extra for.
As always, thank you for your help!
