Has anyone used a hydraulic cement to cement dry rocks for aquascaping?

Is it reef safe?

This one sells at HD

The alk will be off the charts. It takes months to cure, with repeated water changes. Cannot have anything live with it for a loooong time 2-3months

I did not mean to use Hydraulic Cement to create dry rock. It will only be use to attach dry rocks for aquascaping.

Marcorocks sells emarco 4000, somewhat similar to hydraulic cement but very expensive

Here check out couple of threads for the hydraulic cement

Or use the epoxy putty from Home Depot. It's EP-200 and costs under 4 bucks. It's potable water safe for use in drinking water containers, and many people including me have used it in reefs for mounting frags. It does make my skimmer go a little crazy if I mount a bunch of frags at once. It's a 2 part putty that you cut and then kneed together with your fingers till it is completely mixed, and then it hardens, even under water, in about 20 min.

The hydraulic cement is also water safe and for marine. And it cost no more than $10 for 10 lbs
