How to remove marine putty from rocks

[Barlan]

Hi

We're moving soon and need to know how to remove putty from the rocks. It's like when you want a strong bond it's weak, when you want a weak bond it is hard as rock.

How can we break the bond to the rock without breaking our tank? Some rocks we've puttied together in the tank, so I dunno how to get it out cause they're big and heavy.

Any ideas

Will be contacting ppl for help moving it, but maybe we can start to break it up now?

Please help

Big screwdriver and drive it in between the rock and putty.

Putty is very hard, but the rock is soft compared to the putty.
