Let down the righthand-most pool.  This will fill the duck and trigger the gate-opener.  Let down the lefthand-most pool to move the green gate away from the middle.  Let down the center pool, which will split into two pools.  Guide the 2 pools to fill the duck underneath each.  When the blue arm moves to the right end, unleash the pool on the right and it will end up going through the shower pipe opening. Then when the blue arm moves to the left end, unleash the pool on the left to achieve the same.
