So my plants keep falling off my tank wall. They're stuck on there with velcro. Problem is, the velcro's sticky back gets damp and doesn't stick to the tank. So I got some suction cups, but they have metal hooks!

I got some clear silicone for kitchen and bath. It's made by GE and say 100% silicone. I'm thinking I'll use it to secure the plants to the suction cups. I also am going to use it to fix up an old tank I found.
As long as it says 100% silicone it's safe correct?
