Arches, columns and fiberglass rods

[GOSKN5]

Can the driveway markers support some structures that are 20-25 inches high? I'm setting up a deep tank and want to have one or two main structures that are taller... or perhaps an arch type... are these and epoxy strong enough with a good base or am I asking for trouble??

Also share any pics of arches and towers/columns with rods in em etc.. thanks...

I have drilled rocks. It allows to build wathever you feel like by inserting pvc tubes trough them afterwards. Unfortunately the forum doesn't allow me to post pics of my setup

I have used pond foam to hide tubing and that helped glue it all together. At the base i connected a few tubes in a mat so that it spreads the weight and hold everything at the same time

Thanks I'm using the driveway markers tho... can't drill for PVC and don't want to mess with the foam... although would still love to see pics
