Question. Where our automatic Pool cover is and the top of the tile liklne there is a gap. Do I need to caulk this area to keep water from getting into the space? Or is it fine to leave how it is. If I need to caulk it any recommendations on brand or type of caulk? Also there is some grout that connects the top of the tile to the bottom of the pool cover track. Should I clean that out or just caulk around it
