L.bacchus88 Posted February 21, 2016 Share Posted February 21, 2016 I'm in the process of setting up a biocube 29 and I'm wondering about scaping. I want to make sure there are nice spaces for fish to swim through etc so I may want to stack some of the rock- can I use gorilla glue to stick the rocks together/ on top of each other or does anyone else have a better suggestion? Thanks Link to comment
ndrobey Posted February 21, 2016 Share Posted February 21, 2016 Gorilla glue is a poor adhesive in water. You would be better off with reef safe epoxy. Link to comment
ajmckay Posted February 21, 2016 Share Posted February 21, 2016 I don't believe Gorilla glue is reef safe. To attach rocks together I use a combination of super glue gel and underwater epoxy putty and LR rubble. You basically want to make an epoxy sandwich. Thick layer of superglue gel on rock A, then a hunk of epoxy, then another layer of superglue gel, then squish rock B down. Use LR rubble for support where possible if you need to use a ton of epoxy. Also when you've set everything in place take a piece of rubble and texture the epoxy so it looks like rock - Otherwise you'll have fingerprint textures which stand out sometimes. Link to comment
ndrobey Posted February 21, 2016 Share Posted February 21, 2016 I didn't say Gorilla glue isn't reef safe. I'm saying it doesn't stick well in saltwater. Link to comment
L.bacchus88 Posted February 21, 2016 Author Share Posted February 21, 2016 Ok thanks! So that JB epoxy is reef safe I hope lol Link to comment
L.bacchus88 Posted February 21, 2016 Author Share Posted February 21, 2016 Also, if I'm attaching corals to my rock- can I glue them under water? How does that work lol Link to comment
cruiZe Posted February 21, 2016 Share Posted February 21, 2016 Yeah like ajmckay said ... Check this out http://www.nano-reef.com/topic/148730-steviets-how-to-glue-thread/ It explains the superglue / epoxy / superglue sandwich Link to comment
L.bacchus88 Posted February 21, 2016 Author Share Posted February 21, 2016 Awesome thanks! :-) Link to comment
jbb Posted February 21, 2016 Share Posted February 21, 2016 The gorilla glue brand of super glue gel will work on a smaller scale scapes, but the larger rocks will need something a little more . I use this for coral , and occasionally for small rocks Wow that pic is HUGE Link to comment
ajmckay Posted February 21, 2016 Share Posted February 21, 2016 Yeah like ajmckay said ... Check this out http://www.nano-reef.com/topic/148730-steviets-how-to-glue-thread/ It explains the superglue / epoxy / superglue sandwich I was thinking that exact thread but didn't find it right away... I'm doing some of that today Link to comment
CronicReefer Posted February 21, 2016 Share Posted February 21, 2016 http://www.marcorocks.com/aquascape-supplies/e-marco-400/ Use this stuff, forget the epoxy. It basically turns into a cement and it will hold any rock formation you want. I used it in my tank to hold up a 15lb rock horizontally with no issue. Link to comment
L.bacchus88 Posted February 22, 2016 Author Share Posted February 22, 2016 That looks perfect, except I'm poor now. Hahaha do you guys think the super glue gel/epoxy mix is good enough to mount a piece of rock to the back panel of the tank? Link to comment
Pinner Reef Posted February 22, 2016 Share Posted February 22, 2016 Gorilla glue is reef safe. It's just not the best alternative. The sandwich method works the best. The background wall of this tank was built using normal Gorilla Glue. Link to comment

The background wall of this tank was built using normal Gorilla Glue. Fo realz? I swear this came up a while back and the OP got an email response from the mfgr stating that it was not safe for aquarium use. It could be that it was a standard response to avoid potential liability, however it made sense to me. I'd have real trouble putting that stuff in my tank. You're right though the superglue/epoxy method works great. Here's something I did with about 3 quarter size balls of epoxy, some rubble, and a bunch of super glue - that branch is glued to the one rock right below it. Link to comment

The stuff does start to break down and lose it's bond after about 6 months. But that was a mantis tank and he didn't seem to suffer any negative effects. Again, not the best option... but doable.
