2, borax solution: blend 200-300g borax with 100 kg water. Because borax is hard dissolved in cold water, it’s better add 4-5 kg of 45 ℃ warm water first and add the left 95-96 kg more.

3, copper sulfate solution: Blend 30 or 50g copper sulfate in every 100 kg clean water. To avoid poison, we can add a little of limewater.
