UV Dye.

Is it a bad thing putting to much of this stuff into your water?

I poured some dye in, then later found out I only needed about 10 drops, there's probably about 150 - 200 drops in mine

Temps are still the same.. but will it do any damage or anything?

Probably won't do any damage, although it might start to clog up the block and cause more staining on the tubing. Id just keep an eye on temps etc, then when you drain the loop next, take the block apart and give it a good clean.
