How to secure pvc pipe/ dowel in upper glass Tank

[celbii]

Hello all,
I am looking for what is the best method to secure some pvc pipe or dowel like pictured in this link.

It looks like some sort of closet rod holders were used and then some sort of silicone. Does anyone know which sort of silicone and holders to use? And what is sturdy enough?

aquarium silicon will do the trick - as long as you let it cure properly

You can buy little plastic cups made for mounting shower curtain rods and mount them with the aquarium silicon, then just mount the wooden dowels in the cups. This make removing and replacing a dowels easy.
