Any weatherproof silicon caulk will do. I just did this to my pool and went with a clear weatherproof caulk. The color choice is up to you. One thing I would recommend is to add backer rod before reapplying the new caulk. I got 3/8" thick foam backer rod. This can be found at Home Depot, Lowes, and most pool stores. It gives the caulking something to adhere to and fills the gap which is typically too large to fully caulk. Lastly, some people opt to sprinkle fine sand on the caulking before it cures. This does makes it blend into the cement (tile in your case) a little better. Good luck!

Hello all- First time pool owner here. We just opened up our pool and luckily had a friend of the seller show us the ropes. Unfortunately, there was an ongoing issue that they chose to ignore. There are two return jets and they always left one shut off. This is because sand tends to come out of that jet. He said it happens on occasion so they left it off. I tried testing it and sand blew out right away. From what I have read, the most likely cause is a broken lateral. However, every answer I found was when all jets were blowing sand...not just one. Does anyone have any suggestions or ideas as to what it could be? Thanks!
