By the way, don't do that 25g water change you were speaking about. Let your tank fully cycle before changing any water. In the mean time, keep an eye on your ammonia/nitrites/nitrates. Once your ammonia and nitrites have peaked and gone down to 0, and once your nitrates are slowly starting to build, you can do that water change (however I don't think i'd do a 25g waterchange).
Unless you have inverts in your tank, like a clean up crew, and then you dont want that ammonia or nitrites spiking too high. But if you were serious about this hobby, you wouldn't put inverts in a tank while you were cycling... wait until you see that green algae before adding
any type of clean up crew... and make sure your tank is cycled.
Enough jibber jabber, you get the point.
