cementing gluing rocks together

[DKoKoMan]

NYOS Reef Cement works well IME... also epoxy putty if you pull your LR out.

Drill the rock and use acrylic rod to suspend it and then a little epoxy to prevent it from pulling apart. It has worked really well for me, plus it hides most of the joints on the inside of the rock

Does anyone know where in Calgary I could find Acrylic rods?

Order them from reefsupplies.

I'm sad to report that after 2 years, the Fijicrete is starting to crumble in my tank.

I drill holes and use acrylic rod which can be purchased/ordered from most local plexiglass suppliers (last year I paid $5 for 6 ft length of 3/8 dia) and I also use cable ties and then use Quickcrete Hydraulic Cement.

The hydraulic cement cures extremely fast (about 5 minutes) so you don't have much time to work with it, so use small amounts. It can be purchased at Home Depot. Sometimes the Hydraulic cement really is enough by itself as it bonds very well. Here's the link to the Hydraulic Cement at Home Depot.
