Is anyone making DIY rocks, I'm just fishing for ideas about peoples ways of making them...
I've used to recipes, one for base rock:
1-2 Parts cement
1 Part Coral sand
1-2 Parts Aragonite
2 Parts Rocksalt
I made some by laying out 18X8-10 inch slabs of this mix about an inch thick, with areas covered in rock salt and areas that would connect to the next layer (to create short and wide caves though the rock) then smashing it into 8-12 inch chunks after it dried and it came out pretty realistic looking, half way between regular base rock and haitian rock. The with caves and stuff, before i smashed it up, it just looked like an ugly rock with slices through it, but with good flow through the rock itself... Its REALY rough.
Recipe two was for branchy stuff
2-3 parts cement
2 parts aragonite
2 Parts coral sand
1 part rock salt
Mixed pretty wet, but controllable, and piped with a plastic bag (like a pastry bag). and layered over aragonite sand, with multiple layers of branches and holes though the rock... this batch is still drying, but i expect it to be like a stiff matrix of rock, not as good flow through the rock though because of the added cement, but it should be more complex in shape
I don't have a camera, but I will see if i can't get ahold of one soon.
