剛剛在計算這個配方的時候,發現一些問題
裡面的CaCO3需要用酸去溶解才能化開
這在使用上很不方便(無法做成液態)
粉狀的話可能今天要換水,上個禮拜就要裝桶RO水,然後開始打CO2養水了
(是有沒有這麼麻煩阿)
如果使用檸檬酸去溶解的話,又可能造成PH會落在中性甚至酸性
我修改了一下配方,將CaCO3改成CaO
除了無法提供CO3-2之外,生成的離子大致上沒有太大差異
配方如下
成分 分子量 添加量(ml/L)
MgO 40 26.4
MgSO4˙7H2O 246 3.7
CaO 56 15.7
CaCl2˙2H2O 146 1.5
Na2SO4 142 2.5
KCl 74 0.3
溶於水之後可以得到
目標莫耳濃度 離子莫耳數 離子質量
Mg+ 0.675 0.67504065 16.20097561
Ca+2 0.291 0.290631115 11.62524462
Na+ 0.018 0.017605634 0.404929577
K+ 0.004 0.004054054 0.158108108
SO4-2 0.033 0.032646284 3.134043284
Cl- 0.025 0.024601999 0.861069974
其中目標莫耳濃度=jack大算出來的離子濃度/元(分)子量
除了缺少CO3-2離子以外,大致上的組成一樣
至於CO3-2的部分,打CO2進去,一切都解決了XD
由於成分裡面有強鹼,所以搞不好連PH的問題都可以一起解決
以這個配方下去算的話,每20L添加0.47g就夠了
這個量能提升多少PH我很好奇,有沒有哪位高手能算一下?
