Experts recommend turning aquarium water over 5 to 10 times per hour in a fish-only system. In a reef tank, it is recommended the water be turned over a minimum of 10 to 20 times per hour (although many hobbyists prefer a turnover of 40 to 50 times per hour). For example, a 30 gallon reef aquarium should have the water turned over 300 to 600 gallons gallons/hour.
