Aquarium Safe Black Paint to paint CPVC?

Hello!

I'm going to be drilling my live rocks and using CPVC to 'connect' them / stabilize them. That said I'd prefer to have the CPVC black so it's not super obvious/contrasting - but I wasn't sure if I could just pick up any old black spray paint or if I needed something special to be aquarium safe?

Why CPVC?
Its more expensive than regular PVC..

You can easily purchase PVC that has been dyed already..
https://www.bulkreefsupply.com/black...0-pipe-58.html
Amazon,etc.. have it too..

Also.. why would you paint whats going to be covered up in a rock too? You won't see it..

In general there is really no paint that can be applied to PVC that will not flake off over time regardless of preparation,etc..

Some have had good luck with spray paints like Krylon Fusion (not made anymore AFAIK) or just any spray paint intended for plastic provided that proper prep (alcohol wipe down/light sanding,etc..) are done but the second you slide it into a rock you are likely going to scratch it right off..

Either buy colored (dyed) or just skip it IMO..

However.. to answer your "safe or not" question.. Most if not all spray paint is "aquarium safe" once fully cured/dried..

Long term if it is exposed it will be covered with coralline no need to paint

If you want PVC that looks better, used colored:

I have used black krylon fusion on my previous overflow standpipe, no problems noted, although as stated it will simply wear off over time.
