Aquarium Chemistry: Calcite, Aragonite, Limestone, and More — Advanced Aquarist | Aquarist Magazine and Blog
"And, in the words of the chemist-aquarist-author Randy Holmes-Farley "calcium carbonate will not dissolve in the water column of normal marine aquaria". Some may dissolve within a deep sand bed where water chemistry changes from the top of the bed to the bottom, but this is unlikely to have any significant effect on overall water quality. So, I wouldn't waste a minute of my time worrying about whether or not something is made of one or the other, or of dolomite either for that matter."

I saw a guy's tank not too long ago and his 2" aragonite sand bed actually became one giant piece of calcium. It literally melted into a brick. What caused this? I wasn't there to test his ph on a regular basis, but he had fish and inverts living in the tank...

Ph has to get pretty low before the aragonite starts to dissolve, but it does supply a natural substrate.

7 right?
About Randy's article and comment on calcium dissolving- what about cuttlefish bones in aquariums? Am i correct in assuming he feels the same way about this?

Right. But I use it because that is what I found on natural reefs, patches of finer ground mixed with coral rubble. Parrot fish add their fair share to the finer grained particles. It's hilarious watching a group of parrots pooping curtains of fine white sand.

I really appreciate all the feedback, but if I am not keeping corals does calcium come into play? Thanks

I like calcium based substrate for it's buffering capability.
So is calcium something I should be concerned with in a FOWLR tank? I was under the impression that calcium was more for reef tanks. Forgive me this will be my first S/W. So if I sift thru it with a gravel vac every WC like a FW tank I should be ok? Should I probably keep it thin, like 3/4" or less? Thanks in advance

No. it's nothing to be concerned with for a fowlr. As I said, the larger the particles, the more stuff will get caught between them. If you are planning on using a coarse grain, then yes, you'll need to vacuum, but a finer sand and you will not.
I would not want to vacuum my sand bed, even in a FOWLR. lots of things end up living in the sand bed that become food for your fish- I would hate to have to vacuum them out with the fish poop.

I would have some sand sifting gobies and starfish to keep the sand stirred up. And as said, to protect the beneficial stuff living in the sand.

Conch snails are great for mixing up the coral, got few others that mix it up too but can't remember there names. Just watch with sand sifting gobys as like to jump as have just learnt
