Thank you, I'll check that out. I planned on using it to build a glass tank. I'm surprised nobody else chimed in. I've seen this silicone recommended here, and planned on using it. I guess I should probably change that plan

NO silicone manufacturer will recommend you use their silicone in water.

I just built my tank using the 999-a and I went thru the same thing your are now looking for more information.
