Rods to Join Rock

[Jerry Ebner]

I was going to use a Fiberglass Rod from Home Depot . By the mailbox area called "Drive way Marker"
Someone told me the resin in it would leech the water so I looked around and some say yes and some say no.
I went ahead and contacted the MFG of that item and they said they use a Resign in construction of it and it may leech the water. So that leaves me to Would a Acrylic Rod do well and what size best ?

I may just go back to a safe scape and stack the rock safely.

My plan was to Cement the Rock in pieces and connect them with the rods but now thats a bust unless I find another plan.
Any help will be nice
Thanks
Jerry

Acrylic will work, size appropriately for the weight of the rock. I have never done this yet, next tank I'm going to. Also PVC pipe will work.
