Ditto to all of the above, well except for anything re: plants, I only have artificial :-?
Test kits are a really good thing to have, so highly recommend them.
New tank, add fish slowly because your tank is going to go through the cycling process.
If your tank temp is much higher than you require, you could float some ice in a bag, use a fan. I've had to do that sometimes in the summer (winter here now :evil: ). Also, just as a note, when the tank temp goes up, more oxygen is used up, so down the road if needed you could add an airstone to increase surface movement which increases the oxygen (don't know the technical jargon for it :oops: :lol: ). Usually an indicator of low oxygen is fish gasping at the surface.
I don't have any driftwood in my tanks, but from what I've read here they will sometimes realize something in the water called tannins which could give the water a brownish tint I think it is :-? , which doesn't hurt the fish by the way.
