1. What is the water parameter required by CRS?
CRS can adapt to and survive in wide range of pH. The optimal pH range is around 6.3 to 6.8 to show the color well. GH is best keep at around 3 to 6 dH. Nitrite(NO3) best kept within 25ppm.
What is the best method to control these parameter? By chemical? Advice anyone. Thanks.
