Questions
-wat is the meaning of PPM? plz exuse me coz i m still a newbie.
-Like one of the forummer said we can measure potassium permaganate by using Grain[64.79891mg] but i dun think we can get such a sensitive weighting scale mayb we can roughly divide it from 1000mg (1g) 15 times[1000 divide by 64.79891]
-let say i got 600ml of water in a bucket, how much of potassium permaganate should i use?

conclusion(correct me if i m wrong)
-Potassium permaganate and Hydrogen peroxide (H2O2) are used 2 burn bacteria and kill pathogens of a new fish b4 introduce it into the main tank
-some of the forummer said can measure PP by observing the colour of the water when the water and PP are mixed. when the colour of the water change 2 pink then it is safe to dip ur fish for about 10 seconds
-do not dip ur fish too long if it got open wound
-Both H2O2and potassium permaganate can be found in local pharmacies
- potassium permaganate can be discolor or de-activate by dousing H2o2. It clears up pp & de-activates them.

THXs for all the details
