สวัสดีครับ พี่น้องชาว aquac1ub ผมขอฝากเนื้อฝากตัวด้วยครับ
เรื่องมีอยุ่ว่าผมไปเจอเพื่อนแถวบ้านที่เลี้ยงกุ้งเหมือนกัน เขาบอกว่าเขาใช้ชอล์กเขียนกระดานแทนแคลเซียม
ผมไปค้นมาว่าชอล์กมันคือยิปซัม หรือ แคลเซียมซัลเฟต
อยากสอบถามว่ามันใช้กับกุ้งได้จริงหรอครับ มันจะเหมือนเจ้าUFOรึเปล่า{"message":{"xc":null,"xk":[28,15]},"messageType":"client_data"}{"message":{"nj":{"left":13,"top":22,"width":28,"height":28},"Oh":{"src":"https://www.google.com/recaptcha/api2/frame?c=03AHJ_VusJIqFHWMQImuRsBtdNYLCZSFBQk0BJc9awZJHKsFqmbmPrfIuEeJlRAnvMsJ5FZQhBPPpN-YAX0ZJin3HmTOMVFLwScOQT_JLLxA6RfjfiZJRH0rhHXMg6bAW7X1jPrjkhzZfU2gwGgO_qO8yJ3kI3nLt7lhngiAlzwnlttsbRWMwNIADwrCFLmeiUB64NTVODUHpalX156rkDw51ExwsYMXPDhdITN1E-M8S953lEfc9ee4l7LiNOfCQdRaOd1rh8Fh_z9kMQfozHjXrqLTu9DCMZiJieRl6myPvG3JM9q0iYmSNljQjE_8vAmXWh26Zwisxz2Z8RfPv4Ri5RWfwOs6PVUvx-LZ18PBiQ2Cp__d9NzxYivAC-RxfrGPLAHD-adALfS_6PMD9eT82wsjl-kb12b2wX2lnlQnfN45euubTfCnY&hl=th&k=-731144760&v=r20170119101210&bcr=%5B-1325857398%2C1763387053%2C-1165554226%2C-1110748980%2C945792328%2C7829416%2C-224144578%5D&chr=%5B31%2C18%2C92%5D&hr=-433007861&bg=!NDKgMhNHG6AWQT4naOpBOvw7pS3P9GUHAAAAfFcAAADSnASWTz1fb4yIYctpOJYZ8E5E1wRNHnqhSiEz5LDCuO5VJSCp1CGQxf57tPc_xBJeMWwPOCLWTVVCKFD7mMv3OhU6xC69mWIBcTCksfldRDyyK7AsqK5Phb4Fgjj0uF7Nd_v57R40edIhDbCk1g8tPPGET1lZSHT-nwcX-4u6xni7MWhAYpoN2xdGc5zommXaj9BxK6Ft-WfRlVzn_jF8qfZaYIYedv9-XS214eDqFiRI8L11Irk3S_2jqwtsKR1Vc4Jj0dVN6iM_IFlyTwy7kMQQiSa67BOWY2Onbc3awOyjWx5hNCQRHyWoL2O7IITX_dURlEZVinLUiQCZG284THksO30iiPRPqqGeQEWHJXjiyzrh800audXoRNd01mDFbyZvwGvz2C2k0YRrlJjcl1aV9trToq1aC3iylXCtoR6n3Xbb-O7LXRP0lapn1siDl1oQi_4urylFGRTJIugysv2ws1ttlqEXdgfZplGPsJbGHbsWs14v-yjYCYpQKGpGjNYIeHHGqipmfhJGW3h242CGTjgpp-961JxMchP0V6IVSOJNkodBt34e6utku2y_TUtumUJVRc5jNTigqT0zIspExHMorwRcVS7moPFChD1VlDY7JYus6n_EdQMGllSkRT4Yi7oEXuIIoPujfsCVBfYvsUgEE88U3DM74T9NWO1u4XBh0amawJIygQkMwRPFHQaFi_oqq2qMX3appjkBbs6-BARD0KRgcWohgLvwmCBSneGItiiESVI-se1lEgLPsoaJdhveSUR8VGJfvIr06jvPd88xyovFqD2SjgWkcztgaf_qpUsHdwbJMwLxy2MMY-NP2_VnMIoNZ8ry4f89b4DcodugYi0lxiMScP9ymZYC5bAwubNditnZVgbq6Eds1ZnUEqhfsrt0KJ_ObW73HVbmVHJB7FTr-hglCBe4I07OvLkw3tTO4DzeQhFDmK7Jy8Y-JwzZ95thcoG5IBYRXeAZoVtikL2eUn75OkgkwazExJbO8cJ7FhUDVmU1S_kT4wBD0DHPsm3OjJS-iebmZr_SDNsif_C3guqXjBF6K0qYbKNmSU2wEJV7qaiDEtSySRf4C6k2dghf3BWaF6pjPkOe3QGqCMMCIPZMtx2ehOrUY6sO4DLONx47qFm3d2vQ2arK0ynwrjypylAbYjeoEdoxTVC5OP23tYgv1Y0FSirmDaa7owHpQUA57S9NrjvNMsK-RvH4RlLcSQuK-2ABO-aVgNh6UYmjyw_FIbqB6ha3TjDWbOLpnA3E8feOVwHxmcGGDOt3gkvSIJyfGvJvzNwJcEykHz9_vYHUZ53ji5v-gq-TkubgpDHr1Ow_P6l-Pgkro8NTmGYbUJN-Ssn2h7PwcW50HplXeVW8d21ktDlZsXAzI8B3E6OrigdjOFi4xs1JGmO8g0q1BE-fT6w70NrRfz-NPeGsNNd6zm2pmGLINrceDY6w5XraO2fH7oG9Ff7mvWjCo5kmn8SkJP9w-Dsdmbz-N234gdq1SiXaXwqvaNyUHkNxzq91cIdYZgsIBmTYz8uSCW2XZiTceP9OUGGJQAX-OVs8Pg","title":"โจทย์ recaptcha"},"Rg":"y5dgeimiwdkp"},"messageType":"load_challenge"}{"message":{"response":"03AHJ_VuuptMdCYwCr9veWWKVJOfaRrgSDr38ga1RqVL7fwCmhyqiwvWsnxuyIt0rynsZejOsgyP3tDNnUagSGXGywVNJO1kxJT1BTBHuDOGZBI-PFF9W-H6jKDVq7QknD76JwzmUmcVu798pD5P3WC7TrUQ9Aqn7FWa6w1MsYygJWMS5-vYlH3dSKFzM58ZRSf6ozN9N7Hfj3J6I1rr8DHe6pHmtws2H45j5z48c4lNQEYvZWMs4MwkbQkXtPbR1Y337q1yN-t_7lcaf_4uVt8DueaPobz26ygbct-ljeNCmXVuZwnYeWDht3jNQ8HKxaabieAgHvBlRycDXQ5A3kKXWxKUcfHTogPpuhpwXwuL689Noul5bK6KvPMux99DyMqRjmhGG31W8hdaxJPkBZHi0nxj6MRbl8-rwcaoUtH_shEp5J6jZPs_Bgk0B8C6PBzMuzCoPJah279AzmmSay2jS_k-2PEOv_FWC07A3eada5cQaPZXQT1igTZ-8srlq0OPOaU15xm6HPIYvaSIYobL-n_XKD6w3yxjod7HzSRP9qAvPFZ2eEKzmjNXjtk2fU2iFjhpH3bWx7GDcKnw84IxIBWe-_TEKSoAgp2CXo7lp-wFeZYD7Y6WejjhzvpMUBJtwP4S3SOQ7vz48j01zAmsqINI0ITMuxixFZBydqpX2eGOdcdhr8o7OXtZl2hY5LZFViYO5xDx22kNnDtxarRTQKIXn6XhFeS1CYBHdRRBWXOwsT4-iH8TuUdMkSphsTpH8BNTZS3lvlVTKZqNHpS45sRY8Y72rtqZ0evAiFR_7qPd_oOOezu4WoDVVw7qGxOQY5RyvsIZq_vzsm4WtEqsmYlxO7klwY3JPYgGgupmf2KsqBhN82gDvWJOFXZnr1rUJIJ4ksqOk7wMVHIeXkMwoRKXM8ncGW9rEsbjVxSh9y_Az5H1luRelr85wozYQV_X5ZRDncRxY67LBNfOlqX4KkTcN0GB0nJZQpHFtZn3SCfA-4WHsL57gMY8MUH0PGTWVNQMLJUWm3","wk":120},"messageType":"token"}{"message":{"visible":false,"xc":null,"te":{"width":0,"height":0}},"messageType":"show_challenge"}
