Hey guys... quick question. Should you do anything different when cycling a tank that has sand in it versus a tank with gravel? I've had my tank running for about 4 days and those stinkin' danios are making a mess of my fine aquarium... lol. Anyways, I'm going to buy one of those batter-powered vacuums tonight (for picking up left over flakes on the sand) and hopefully clean it all up. But yeah. Anything I should keep in mind when cycling? I'll probably do my first cycle in about a week, as not to screw up the new bacteria/whatever.
