Please explain. I do not even know what Tufa is. (I do know what troughs are.)

Perlite may be used in place of half the sand to reduce weight but finish
will be less stone-like. <<
Okay, starting to get the idea.... But now for this RECIPE... What the HECK
is SHARP sand and PORTLAND cement?!?!?
I only know Play sand & don't have time to go to Oregon for cement. Please
advise. Is it really good for iris?
