I'm planning my tank transfer for the next couple weeks/months. One thing that I really want to be perfect is the rockscape. I usually just place rocks on top of each other until they are somewhat steady. However, I usually don't really like such scapes long term. I want more open space in between.
Now I could of course use something like mortar to secure the rocks together, but as I understand it mortar takes quite a while to cure. I'll be using live rock that's currently in my DT and I want to move all rock, fish and corals in the new tank within a day. So unfortunately, I don't really have the time to wait for stuff to cure.
That's when I came across a guy on youtube that uses cotton wool, super glue and sand (to hide the wool) to secure rocks and wood together. It's as simple as putting some wool in between 2 rocks, a good dab of glue and some sand to hide the ugly stuff. I assume this might not hold unsupported rocks long term, so my idea is to initially use the cotton wool tactic and then use reef safe 2 part epoxy putty to get a stronger bond. The glue hardens extremely quickly and the putty continues to harden under water.
This is the video I'm talking about, around the 34 minute mark:
Could this work? Will it be a strong enough bond to hold an unsupported rock?
