Bathroom mould

[blacknife]

I was pulling out the cracked silicone around my bathtub liner to redo it and the bottom 6-8 inches all around is black with mould.

now… if I was working and had more money right now i would just redo the whole thing, but I am un-employed and near broke.

I was thinking of just re-caulking the whole thing to prevent more moisture from getting in there and then redoing the bathroom when I have more $$ anyone have any thoughts on this?
