Light colored nutrient substrate?

[Heather H]

Hi all! I'm getting ready to replant my planted tank into a larger 40g breeder. My old tank has a mix of natural gold colored gravel. I used caribsea red under the gravel for the plants & it worked fine when i gravel vacuumed if some of it got pulled to the surface because it blended with the gravel. My new tank will have light colored gravel (peisces silver pearl from amazon). Does anyone know of a light(er/ish) colored plant substrate that I can use under the gravel? I don't plan on using carpeting plants so I will definitely need to be able to gravel vac & I don't want to have a dark substrate get pulled up & mixed in.

All the plant substrate I've seen has been medium to dark colored so that seems a hard thing to do. The only thing I found when looking around the internet was an article that mentions "best planted substrates" and the lightest one on it is a sand: Carib Sea Super Natural Moonlight.
