Aquarium safe silicone for aquascaping

[Reaper_Six_Four]

planning my aquascape at the moment.

Has anyone used aquarium safe silicone to put rocks together instead of super glue gel or epoxy?

Curious why this isn’t done instead.

I wouldn't just because the cure time the silicone takes to dry, plus since it stays soft/ pliable, I would bet rocks wouldn't hold together long term.

I'mUsing thin superglue and pouring sand over the wet glue makes the glue dry almost instant and produces a great bond. Reapply and add layers to strengthen joints. Using this method I can hold my top rock and hang the rest of the 15lbs beneath it. (For my current project)

I second this! @Gluemasters and Marco rock powder.

Super glue with baking soda is amazing. Then add a sprinkle of rock dust on top with super glue to blend the look
