Underwater Epoxy/glue

[richiestang_78]

I recently redid my aquarium and have a nice rock slide. I thought my stack job was pretty good however a few rocks are a bit more unstable then I feel comfortable with especially given the fact my cories like to hide in them. Is there a good underwater adhesive I can use to just lightly secure the rocks in a few places? The tank is planted is that matters.

There's aquarium safe silicone and cement. Also super glue could work.

I'm sorry I guess I worded it wrong, is there an adhesive that will work in the water?

“In the water” does limit your options. You can drain the tank to expose the loose rocks, apply the adhesive (silicone, superglue), allow it cure, and then refill it.
I did find this product that might suit your needs. I do not have any experience with it. It is called FAUNA MARIN AQUA SCAPEFIX

I know JB Weld makes Waterweld and it is apparently safe for potable water. And a few reef forums say its reef safe.

There's also something called Mr. Sticky's Underwater Glue.

I cant really drain the water far enough to do what I need, I don't need a lot of adhesion just want to put a dab here and there to make sure the rocks don't slip

This was recommended to me for bonding *wet* things together, whether it would work IN the water I'm not sure buy as it IS a gel perhaps......
