Hello, all,

I have a leak in my water garden that came from a root that grew between the pond liner and the plate that attaches to the skimmer (did I explain that well enough?). My question is what is the best material to attach the plate to the skimmer. I am thinking of two materials, the first is a silicone caulking, and the second is something like a water fall foam.

My thought is that both would be similar since they are water resistant and are sealants. I like the foam idea because it seems like the expanding foam would do a good job at sealing, however, the people who installed my water garden used the silicone.

In either case, what is the best place to buy the material? Does somewhere like Home Depot or Lowes sell it, or should I order from a place on the Internet? Any suggestions?

Thanks to all for your help.

Tim
