Hello,

I used a product manufactured by a company called "Boatlife". It is a marine caulk made from silicone. When I purchased it, I was told that it was made specifically for "in water" application. In addition to caulking the seam where the skimmer meets the liner on the inside of the pool, I also caulked, as best I could, the seam over which the water flows when going into the skimmer and into the basket. All caulking was done with the skimmer dry and fully exposed to the air. The caulking was allowed to cure in the open air for 24 hours before I filled the pool with enough water to operate the skimmer.
