sharpie ink underwater?

[JohnK]

I'm trying to figure out a way to catalog the frags I'm raising.

Does anyone know if sharpie ink will cause any problems in the tank?

I was thinking of using plastic plant/flower tags attached to frags with fising line. My idea is to use a sharpie to write a number on a tag for each frag.

Any input? Is sharpie ink toxic at all? (I'd let it dry before putting in the tank)

id be more incline to write on the glass of the tank

You could always just take a picture of the frag and label the file the name of the coral

what about a labeler, one of the punch labels that doesn't use any chemicals, then attaching it to the frag somehow??

Won't the labels end up getting covered in coralline after a while?

Sharpies use an alcohol-based solvent, but that evaporates as soon as it dries. I don't know if the dye itself would wear away in the salt water over time, but I doubt it would be toxic. Color-coding with plastic colored toothpicks is also an option.

Sharpies do erode compact discs....... i'm not sure if i would want that in my tank

Thanks for the suggestions.

I'm looking to mark each frag somehow so I can keep track of individual ones, (ie I take 5 frags of a particular coral at the same time, joe schmoe asks me to save the one in the middle, a tag would make it a lot easier to keep track of that particular one)

The labeler sounds like a good idea. Maybe I'll give that a shot.

No worries using it.It will wear away after a few months though.
