I have had luck with an epoxy/superglue combination, but I did use the stuff marketed for aquarium use so it was obviously overpriced. I've used the stuff from Petco/Smart and from BRS. This seems to be the best deal but idk how much you need...Yea i am gonna have to break down and use marco or nyos i am a gan of aquaforest but heard its a little hardto work with....nyos is a quick set so should help accomplish what i need but am going to have to go with dry rock for this and use what pieces will fit of the tank rock. from my research sounds like mortar and wet rock take forever to cure....and would cause some die off in the process.
