the bottom of my tank(where that black outline thing is at) has that "calcium" stuff on it.....should i be worried about this? what does this mean? HELP...lol

no, dont worry.
just make sure your levels are not too high and causing it to precipitate out (because that can also damage your pumps). but if its just corraline algae dont worry.

its calcium deposits on the bottom band of the tank.....maybe i 4got to clean the lil bit of water that dripped down when i did a W/C

If it is on the outside of the tank it probably spilled out.

If it is near the top of the tank it is most likely "salt creep".
