I wouldn't even bother dosing yet.. you should be fine with just water changes.

These things are only needed once you get into calcium demanding corals.

I hate scraping the coralline off my thermometer also. Each time I remove the thermometer it's hard to stick back on the tank because the suction cups are old and crusty.

I have the stick on kind and it is as accurate as anything else I have used. Plus you dont have yet another Item hanging in your tank.
