I had this problem yesterday. For some reason the liquid turns black. Unless this problem is solved, this liquid cannot be used, so I tried to find a solution. I just discovered the cause and solution after a lot of trial and error since yesterday. I didn't know the theory so I looked for it in the official forum and got a clue. I will update one image to its original form. ๆจๆฅใใฎๅ้กใซ้ญ้ใใพใใใใชใใๆถฒไฝใ้ปใใชใใพใใ ใใฎๅ้กใ่งฃๆฑบใใชใ้ใใใใฎๆถฒไฝใไฝฟใใชใใฎใง่งฃๆฑบๆนๆณใๆขใใพใใใ ๆจๆฅใใ่ฉฆ่ก้ฏ่ชคใ็นฐใ่ฟใใฆๅๅ ใจ่งฃๆฑบๆนๆณใๅ ใปใฉ็บ่ฆใใพใใใใ ็่ซใใใใใชใใฃใใฎใงๅ ฌๅผใใฉใผใฉใ ใงๆขใใใจใใใใใณใใๅพใใใพใใใ 1ๆใฎ็ปๅใๆฌๆฅใฎๅฝขใซใขใใใใผใใใพใใ
