i looked up some article, it say 1.008 can explosive the white spots
Only part of the white spots will be removed but still some of the spots will keep silent in the tank. When the SG increase to 1.02, the silent one will come back again.
I have tried this method for many times and everytime, when the SG increase, the white spot came back again.
Why not use Copper?
