Selecting gravel for an Angelfish tank

[tanker]

Not at all if you use pool filter sand! Yawn. No stirring up, no dust, no affect on water chemistry. I have mine over an inch deep in places, but because I use the sand to hold down peat, I purposely don't have it so deep the roots won't reach the peat. Sand is a great substrate, if you choose the right sand!

I stand corrected. When I hear "sand" I think that fine stuff (the same in my SW tank), too fine IMO--but that pool sand sounds OK.
