In my 10 ton breeding pond, 18 carp measuring 50-70 cm were being bred. Spring water was circulated between the tank and two small stone compartments. However I felt there was insufficient air supply and thought that installation of a 1 ton container tank with oyster shells would compensate.
However, feed was not properly given this year and due to poor water quality, the carp developed a yellowish appearance by the beginning of August. There was a strong foul odor and impurities were found in the filter equipment. At this time, I happened to obtain ECOBIO-BLOCK and added 20 blocks to the 1 ton container tank.
Within 1 week, the foul odor was eliminated and the carp appeared whiter as the water cleared. Feces was not accumulating, so I decided to continue use.
