I’m an area of shallow reef 1-hectare in size and 1 m deep (=10,000 m3 or 10,000,000 liters) has 100 individual sponges, each of
which is pumping 1000 liters per hour, how many liters of seawater is being pumped through sponges in this area each day (24 hours) And what percent of the water over this section of reef is passing through the sponges each day?
