Hi, I've just bought a tank 450x450x1140 approx. 230L and am a newbie with Tropical fish ( had cold water tanks before ) I'm wanting to set it up for tropical fish, and was wondering should I go with Under gravel and a Power head, or do I need to go to a cannister filter, I am on a budget so I need the cheapest most efficient method. Also Do I need to run 2 heaters or can I use 1, and what wattage heaters should I get ?
Thanks,
Glen
