homemade coral rock <for jun >

i came across a recipe for homemade coral rock and i know jun is good with stuff like this so i thought i,d post it to see if anybody,,<or jun> wants to try it . i think i would only be happy using it on pemphis, anyway its 1 part white cement 2 parts coral sand < but any should be ok > and 3 parts rock salt . mix the sand and cement fairly dry then add the rock salt, then make rocks . leave for a few days to go hard then soak in water for a month, and all the salt disolves leaving holes through the rock . they use it for sea aquariums because its more enviromentaly friendly than ripping up reefs . i have not tried it myself because i,v only got 1 pemphis and it does,nt need rock. regards john

Surely John I'll try it as soon as possible and post the result here. Probably I'll go further with the design (not just coral imitation) if the materials turns out Okey.

Thanks!
