Reef Cement

[Jaws]

Just wondering if anyone has a link for DIY reef cement for cementing dry rock together? There's a ton online but I'd rather go with a suggestion from someone I know from the board than some random. This stuff looks great but it doesn't look like it's available in Canada:

Ideally I'm looking for something with quick drying time, stable pH, and that's obviously not going to leach anything into the water column. It's for a 400G tank so I have a lot of rock to work with, hence why I want to use a DIY product instead of purchasing epoxy. Thanks for your help.
