repair coral viewer

[Jimmyneptune]

I have a sea side aquatics coral viewer that has a slow leak. the viewer starts to fill up with water over 15-30 minutes when floating on the water. What can I use to repair the coral viewer?

I would take a thin layer of clear silicone and seal the side that goes into the water. Just be sure not to get a lot of silicone on the clear plastic. You could seal it from the inside too. Be sure not to put it into the water until the salt and vinegar smell is no longer present.

A couple drops of the right Weld On # or a similar solvent adhesive applied heat the seam should seal it right up. Silicone will look like a hack and may or may not stick long term. Use some citric acid and an RO rinse before the solvent though. You want to get any salt or calcium buildup out of the leak path so it can be filled.
