Rock Scaping
Just wanted to compile a list of how people make their aquascape stronger
ive heard of people using , acrylic rods , cable ties , eboxy glue , slilicon , foams , concrete and kneading materials but what is the best ? which method allows you to readily change your aquascape?

also many different types of rock have been used examples are just normal cured and uncured live rock , dead live rock , base rock and my favourite texas holey rock !
what have people found to most readily accept purple coraline algae?
whats better in terms of creatign a lastly aquascape ? better to drill for rods or cable ties?
thanks
Tim
