Silicone not sticking??

[logger850]

I am trying to build a plant refugium, trying to glue in some baffles in a 25 gallon long rubbermade container. It's been over 24 hours, and the silicone glue just pulls away from the container with little pressure. I've used silicone before on glass tanks and obviously works well, is there something that needs to be done to the rubbermade container for the silicone to adhere to??

I would try to scuff/sand the area that you are gluing to. I dont even know if that would stick.

Probably won't get it to stick good, might want to try some type of epoxy
