系統開始的首半年，只需一星期餵食 2 次。每次餵極少分量，讓魚兒在 90 秒內食完。由於金魚沒有胃部，牠們並不會因為飽而停止進食，所以過分餵飼有可能令牠們因過飽而喪命！如果金魚排出長長的魚糞，便證明牠們已進食過量了。During the first six month of setting up the system, only two feeds weekly are required. Beware of the quantity, so that the fish finished eating within 90 seconds. Because goldfish do not have stomach, they never stop eating and can be overfeed easily. If goldfish discharge long fish manure, it indicates they have consumed too much.
