龙袍 is 10 1/2 inch
Geisha: 9 1/2 inch
yellow butterfly is 9 inch.
I am starting PP (POTASSIUM PERMANGANATE)treatment weekly. It is suppose to be 1 1/2 teaspoon.. but my pond color always turned to brownish yellow very quickly, so I always did another 2 more teaspoon.
after 2 hrs, add 1 ~2 teaspoon of sodium thiosolfate.
1/2 hrs later, add 1 - 1.5 quarter of Hydrogen Peroxide ..
龙袍 seems little stressed by this treatment...
