Thanks for all the kind words, guys.
Hey Matt, thanks for the question. I did add a bit about base rock and lava rock above, but to answer your question, I do not believe in using lava rock because it will not react to denitrification in the aquarium and will serve no purpose other than aesthetics. Also, it is a little too smooth, making it a bit ineffective in saltwater as well.
As far as play sand is concerned, I really do not care for it, but it can be used. The reason I do not like it is because it does not have the buffering capacity that aragonite sand has. It is still usable in a saltwater aquarium, though.
Keep the comments and questions coming!
