marking frag disks

Postby 120gallons » Fri Nov 07, 2008 11:36 am

Does anyone know if it is safe to write on the bottom of a frag disk with a sharpie or pencil for identification? Any toxicity?

I'm gonna move this into the Asexual Coral Prop forum - might get better attention there.

I know I have used a permanent marker on something in the water and it did not cause any problems. Just made sure it was completely dried before putting it in the water.

I would not hesitate to use a pencil. Pencil lead is made from graphite / clay. Should be fine. But I would worry about how long it would last before it washed off.

Who knows what is in a sharpie - I would probably not use that.

I would recommend a crayon. The ingredient (wax) should be safe, and its hydrophobic nature should mean that will be resistant to washing off.

Sharpie is just fine--wax pencil is fine too, pencil is fine--all good. Just make sure the marker ink is dry first, just to be safe.

Agreed, Sharpies are perfectly safe.
