Hi all. . . . .

I have been considering for sometime of switching from pea sized
gravel to 1-3 inches of fine sand. It is a 50 gallon long tank with 1
oscar, 4 giant danios, 1 plec, and 1 dragon fish (which would love to
burrow in the sand.) The pet store only has sal****er and Aragamax
Sand. What is exactly Aragamax Sand? Is it intended for FRESHWATER
tanks? Does it contain salt? Would my box filter suck it all up? BTW,
I don't have a UGF installed. Thanks in advance!
