Hey folks...

So i'm putting my old/bleached rock together and i need some advice on reef safe cement to bond the rocks together.

Do you think i can use this HomeDepot cement below:

I hear that Aqua-Mend is a item that was at Home depot or lowes. It is safe for all uses Good luck on your build.

Jb water weld works and is safe

Basically the same stuff you can get for 4 times the price at your LFS

Forget the two part tube part epoxies, they are crap for cementing rocks. You need hydraulic cement (meant for underwater) and preferably create your rock work outside the tank. Home depot sells small quantities of the stuff in small milk type containers (can't remember the name). Better to also drill the rock and reinforce with acrylic rods and then cement together. Let set for a hour or so and then put back in the tank. If worried about drying out then cover with tank soaked wet rags.
