* The use of black silicone facilitates the camouflage of possible defects that allow the polystyrene to be visualized.
* The use of cyanoacrylate type adhesives dissolves the foam, they are not valid for this technique.
** The use of pieces larger than that size makes handling and adhesion very difficult.
MISTAKES OF THE TECHNIQUE:
- Styrofoam is sometimes not enough to hold all the weight of the stone. Next time it will be better to use extruded polystyrene.
ADVANTAGES OF THE TECHNIQUE:
- You can achieve almost every shape you want using stones (better to use easy to break ones)
DRAWBACKS:
- Time demanding.
Styrofoam base before final adjustement.
First stages of the process. Please note these are 6 different pieces. They were moved to the tank separately and then fixed with inoxsteel and silicone.
In here two of the secrets, enough space for soil to grow rotalas. And a 6 pieces structure.
* Check in the final photos that rotala roots have past the styrofoam and the rocks and are hanging from the towers.
