I know I have a few PC bulbs, and a few fixtures.... if you are ever in the area with a bit of trunk space.
Honestly, the reflectors in mine were so awful, I was happy to see them go, the light itself from them was pretty good, if not terribly efficient in my case... but once bulbs were like $50 each, I noped my way out. everything is LED now, not planning to look back and think I should use T5s on a display tank, it is so not worth thr trouble.
As for sando, I am intrigued by red flint sand that they find in IL and WI... there also used to be some sand available from Pittsburgh PA that looked pretty OK too... If I ever drive cross country I will bring you a few bags
