  1. Hi Toga, A) Instead of only 1 hose outlet pumping into grow bed, perhaps increase this to 3 or 4 outlets. I will open outlet wider, it have valve for I adjust water flowC) Instead of 6 minute pump cycles, increase this to 20mins On / 60mins Off... or more. I will increase the cycles to 20 mins on/ 60 mins off , 10 times / day D) Keep fish feeding to a minimum whilst mortality continue. I already decrease feeding.
