Concrete/Cement help

[jd1206]

I plan on using quikrete fast set underlayment concrete in an upcoming project. Any thoughts?

Also do I need to spray the concrete with vinegar, or can I simply soak it in a vinegar/water solution?

Any help would be greatly appreciated

from what I have researched you can soak in in water / vinigar, but I would love to get a solid answer on this myself. I am going to be building a multi level water fall frog tank in the future and think I might want to use this method instead of or mixed with the gs / silicone method.
