There aren't great places near me where you can get aquarium equipment, so I ordered gravel online. Now that I have it, I'm noticing it's EXTREMELY small. It's very fine, like sand, and though it says gravel on the back (with the usual advice to rinse it off) and appears to be gravel, the pieces are so small and thin I'm concerned. Does this really matter? I have an undergravel filter, but I wasn't sure about using it anyway.
Can I use my undergravel filter with such small gravel?
Will I likely have problems with this gravel when I use a gravel vacuum?
My tank isn't up and running yet and it's not too late to get different gravel--but it's going to be a pain to send this back and my budget is tight, so if I can make it work I'd like to.
