Flow rates for reef tanks vary depending on the size and type of tank,but an ideal flow rate for most reef tanks is around1,000 to 1,500 gallons per hour. In general,the higher the flow rate,the faster the water will circulate and the more oxygen and nutrients the tank will receive.

How to choose the right flow rate for your reef aquarium?
The type of flow pattern that you choose should ultimately reflect the type of creatures that you are keeping in your reef aquarium. For soft corals or LPS corals, it might be best to lean towards a flow rate that is lower but make sure that the flow pattern is still covering the entirety of the tank.
How much water does a coral reef tank need?
For soft corals and LPS corals aim for at least 20 times turn over, and for SPS corals, at least 50 times tank volume turnover per hour. So for a 250 litre reef tank, it needs a minimum flow of 5000lph and for SPS corals it would need 12500lph.
What is the minimum flow for a 250 litre reef tank?
So for a 250 litre reef tank, it needs a minimum flow of 5000lph and for SPS corals it would need 12500lph. The amount of decor you have in the tank, and how its placed, will negatively affect flow.
What is back and forth flow in a reef tank?
The back and forth motion of these flow patterns ensure that the tank is moving its entire water system around the reef aquarium. The consistent back and forth motion is really good for SPS corals that demand higher rates of turnover in their reef tanks. How much water flow should a reef tank have?
