If it's white "Texas Holey Rock" it originated in the Caribbean Sea and will be fine as a base. If the Rock is red in coloration it's volcanic and can play hell on the PH as well as PO4 and salinity as the elements leach.
Switching from Freshwater to Saltwater.

Ok, I have a few questions that pertain to fresh water relative to salt water products. I have Lots of crushed coral substrate, is that "live rock"? Will live rock or a similar substrate function similarly for fresh water tanks basically adding beneficial filtration media to a tank given adequate current in the tank??? To be more pointed in my last question could I create a filter-less power-head driven FW tank for say cichlids with a live rock substrate???
Awesome article I do plan to start a small SW tank in the next year. I'm currently exploring planted aqua scaping with my sights set on expanding to SW after I get a handle on that.

Saltwater bacteria are different species and therefore don't culture in the same way. I can't explain the ins and outs of why it doesn't work the exact same way but it just doesn't. Nitrifying bacteria grow anywhere they can and therefore would populate the live rock but it won't yield an environment where denitrification can occur as far as I'm aware.
It would be curious to see how efficient a FOWLR - freshwater tank would be in biofiltration.

I also was thinking it might be a cheaper bio media per volume than those blasted ceramic rings, lol.
Instead of ceramic rings... there is a product out there that's hard like rings but is in the shape of stars and like a quarter of the price. I can't remember what they are called. Petsmart has them. Ill post the name when I find it. They are supposed to hold a lot more bacteria than ceramic rings.

I had a great experience with a poorly filtered tank with only live rock substrate and some holly rock decor. I will agree nitrates don't go anywere but then again nothing in freshwater filtration really removes them anyways. Water changes it is.
