  • What kinds of bacteria are used in the tanks?!!

  • Naturally occurring bacteria that is in the air you breathe will colonise the system naturally. The names of the bacteria are Nitrosomonas and Nitrobacter species. Google "Nitrogen Cycle" for more information.

    Hai,

    I am Nagaraj from Chennai, INDIA. can I have ur contact details for even I am planning to start a similar system. I need a good lot of info regarding this... Kindly help me ASAP...

  • @bobx1990 Nitrobaccilus, nitrospira, nitrobacter and nitrosamonas probably.

  • @avitoyee there is a family of bacteria call "Nitrosomas" that convert the ammonia to nitrite. i've been using fish tank waste water for years on plants and even given to friends that have had yard plant issues. the effect the fish water has on the plants is astounding.

  • so, if you have your balance right water replacement should be to top off evaporated water. if you do need to change water you would do it gradually over several days as you don't want to shock your fish. of course each case if different and you might need to change out a lot of water if you have a sever ammonia build up.

  • Greenfrog, I'm looking at this as an aquarium keeper. I have just started to look at this aquaponic systems. regarding your question about removing the fish waste. In a fish tank you don't remove all the water under normal conditions so i would asume the same here. you have to keep in mind that the waste is what generates the nitrogen cycle. waste----->ammonia------->-nit­rite------>-nitrate-------plan­t food.

  • Wrong, ammonia is preferred by plants then nitrite then nitrate, due to the reduction of nitrate requires more energy from the plant than of nitrite, then ammonia. There should be no concern about nitrifying bacteria growing in the system, they are useless. Plant is the great member of nitrogen cycle, not bacteria.

  • can you tell me the level of ammonia leaving the tank and the level of nitrate re-entering the tank. Also the Ph level at both pionts. ??
