The *tube sand* that I know about (and use for traction during the
winter) is a larger grit than play sand, that's for sure. = /
Found that out when one of the tubes got a hole poked in it (sharp
metal), which isn't easy to do with tube sand. The bags are really
tuff.
The sand for concrete is a bit smaller than tube sand.
Is "builder's" and the sand for mixing concrete the same stuff?

Yes. It's much coarser than play sand which is a step above powder at the
Lowe's and HD where I live.

mentioned it, as well as you RM. I just know about the concrete type
and the tube (or traction) sand.
Right now I've got 4 tubes of it on the garage floor waiting until
winter. = )

Tubes? What do you mean "tubes" of it? Here it's sold in 50lb bags like
the play sand.

I didn't know that sand like these would be safe for aquariums.
I knew some folks get their gravel from building supply places, but
had no idea about the types of sand that can be used too.
Is it prepared the same way, just rinse and use?

That's also what I'm trying to find out. I would think even this coarse
builder's sand would be hard to rinse. I don't mind cloudy water in the
tank for a few days but wouldn't want it all the time.
