  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. I make all test for all three tank, please open my attach file Couple of picture for my mortarily Thank Tam Monitoring LH mode

The rate of mortality continue increase,
  8. Hi Toga, Are they 3 separated tanks each with their own separated grow beds ? Yes, they are Do not transfer anything between the tanks or grow beds I used only one net for three tanks.
