Hi all, I've been reading a lot about nano-reefs in books and on multiple forums and I found it so fascinating that I decided to set up an aquarium myself. I bought a 24 gallon Aquapod aquarium (64w pc version) with the factory stand (which I might replace with a cabinet because it doesn't seem very stable). It arrived today, so I filled it up with tap water to check for leaks. I am planning to keep tap water in it for 2 days or so, but after that I'll clean it out and plan to purchase 30 pounds of live sand. Does this seem like the right amount (the base of the aquarium is 19x17 inches)? Also, I am planning to buy 'Nature's ocean bio-activ live aragonite live sand' at Petco, do you think this is ok?
