I just bought everything I need to make my new Recirculating DWC...The one thing I dont have is very important....sealant(to prevent leaks). What type of sealant is ok to use underwater and that doesnt have any harmful chemicals...Home Depot carries caulking as well as silicon caulking!?!?

Go to home depot and in the silicone section there is one that is for fish aquariums. Thats what I use. Its may take a minute to find cause there is about 100 silicones on the shelf. WM
