  1. Hi Toga, Thank for your help, Today, my morality issues stop, do not have any fish die I had feed them, them seem so hungry after 4 days don't eat any thing I will add more fish tomorrow, With my tomato, it have some bug, See picture for more detail, Can you advice me some way? How can I use for kill them? Thank! Tam
  2. Dear Vkn, I would have started with small fish numbers or much smaller healthy fish for starters. Your starter fish looks much bigger to me. What about your plants? I bought fish with 6g/ individual. With my plant, I plant 4 tomato/ 1m2, , plant seem deficient nutrient (as picture I attach), 11 days after I plant in grow bed Dear Toga, 9% Salinity = 90,000mg/l I follow your advice, with add 2g/ 800l of each tank today Have mortality rates decreased since you started water changes ? The rate of mortality continue increase, As you see my record, the mortality continue increase, Even I stop feed fish, the belly of fish so big, some fish have different swimming pattern, sign of deficient of oxy, Hope adding salt can help fish stop die, Thank all, Tam
  3. 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. Maintaining farm hygiene is paramount. Thank for your advice I had never done any hygiene - Sterilize your nets (soak in very strong salt water works OK) The best way when using net for all three tankI note your pH has risen since you started.a) What is the pH of your source water before you add it to your fish tanks ?b) Where is this source water from ? (ie: A dam, river, well, bore, city tap water, collected rain water)c) Do you store your water before use ? and if so - What is the material of the container ? (ie: plastic, concrete, earth dam, rubber liner)c) Did you pH test your sand before purchase/use ? a) PH is 7.8 before I add it to my fish tank b) Well in ground (used to water plant, plant was grown in soil), collect water from rain c) No. I just pump the water from well to every tank d) I did not test PH of sand I have just test it, PH is 7.4 Disease Mitigation - (This is why adding salt is good - search this forum) Can you help me find position of adding salt way? I can not find it
  4. Dear Ande, I'm so sorry for my misunderstanding, This is first time I reply in forum. Tam

  6. Dear all, I had started new IAVS system. Fish tank is 800l, plant area tank is 400l, I had 3 system like that I use the silicate sand, After 3 days after I add fishs in tank, fish still have die - 1 fish die / day/ tank. Every tank I add 40 fish/tank; 6g/1 fish; I feed fish with 6g of fish feed/ tank Now in tank1 have 3 fish die, tank2 have 3 fish die, tank3 have 2 fish die. I make test with water today, with all information like: NO2 0,1 mg/l; NO3 1-->10mg/l; SiO2 3mg/l; PH 7,8; O2 8mg/l I think I not washing sand enough before, so SiO2 so high, it make fish die Please help me, is this the cause, how I can determine this Thank, Tam
