Help--

Setting up 75 Gal Reef Tank for first time. When noticed that
temperature was not changing after adding heater, I realized that there
was a chip in the thermometer. It's a red-dye in-tank thermometer. Do
I need to start from beginning? From what I've read--it's only alcohol
and red dye. Have only added live sand, and salt-water. Was planning
on adding live-rock tomorrow for 8 week cycle.

Any advice?

Thanks,
