Hi what would be the best glue to use to glue plastic tubing to small
plastic pots that would be full of water. I was going to use silicone
sealant but it says not to use in permanently damp conditions. The joint
would in water all the time.

Fish-tanks are glued with silicone. The warning is probably about the
tendency for cheap silicones to grow mould in damp air.
