zero defect

The embedded video you saw  about the beautiful aquarium transcends.This is not something impossible,this is certainly possible if we wanted and give some attention.
In the bible it was told that even if a man looks at a woman with bad intention he has done adultery already.It is very true .There should not be any defect  in certain thing and requires zero defect.This implies to aquarium maintenance also.I am going to give a quiz and the range from 1 to 10. for each question.In the question marked * you must score 8 and less than that you fail in the quiz. Judge correctly.

1)water change------------------------------------------------------------------------------                *

2)feeding------------------------------------------------------------------------------------=

3)nitrite content-----------------------------------------------------------------------------               *

4)waste deposit cleaning-----------------------------------------------------------------

5)tank inside and outside cleaning-----------------------------------------------------

6)fish population----------------------------------------------------------------------------                 *

7)filter system------------------------------------------------------------------------------                  *

1.If you score less than 8 in the astrich marked you fail in the quiz.
2.If you score less than 51 you fail in the quiz and if you score more than 51,it is very good.

start the quiz.
