Negative Space Aquascape Methods

[DeniseAndy]

Yep, I pulled out my rock and glued and then replaced after quick rinse. No issues.

This is what I created using both method superglue as well as E-marco. All the rocks were cured before hand for 2 years.

I've never used the glue, but I have used putty on wet rock directly in the tank. Worked great.

Mr Frog,
Which putty did you use? I tried Two Fishes Aqua Stix and it takes a LONG time to begin hardening.
