Hello:
I'm pretty new to this fish scene. We recently opened a restraunt and have purchased a 200 gallon aquarium for display. This is the first week the tank has been up & running. My father bought a piranha fish which is about 13" and also an Arowana, its a long silver fish(really ugly) which is about 15"-18". Whats the best way to change the water? Should I dump 25% of the water then bring a hose in from outside and let it run inside the tank? Or should I just keep on filling buckets full of water and pour it in? Any good advice will help.
